The "sign of the cross" is found in almost all cultures and generally signifies religious or cosmic significance, e.g. the four corners of the cosmos. The sign of the cross was the ideogram of An, the Sumerian giver of all life from which rained down the seeds of life on all worlds including the worlds of the gods. An of the cross gave life to the gods, and to woman and man.

The symbol of the cross is in fact associated with innumerable gods and goddesses, including Anu of the ancient Egyptians (the "key of life"), the Egyptian God Seb, the Goddess Nut, the God Horus (the hawk),

as well as Christ and the Mayan and Aztec God, Quetzocoatl. For example, like the Catholics, the Mayas and Aztecs adorned their temples with the sign of the cross. Quetzocoatl, like Jesus, was a god of the cross.

In China the equilateral cross is represented as within a square which represents the Earth, the meaning of which is: "God made the Earth in the form of a cross." It is noteworthy that the Chinese cross-in-a-box can also be likened to the swastika--also referred to as the "gammadion" which is one of the names of the Lord God: "Tetragammadion"

Swastikas, the crooked cross, also appear across cultures and is associated with the gods, with the heavens, with the creation of the Earth, e.g., the four corners of the Earth, and the four corners of the heavens; and with sexuality, the fertility of the Earth. The swastika is a sex symbol. Four men or women lying together on their sides engaged in mutual masturbation and oral-anal sex.

The commonalty in religious significance associated with the cross may have to do with the "four corners" of the world and the heavens. As ancient priests and shamans turned their eyes to the heavens, seeking to peer beyond the mystery that separated this world from the next, the "four corners" may have been a common astronomical deduction, a way of dividing the divine circle into four equal parts for navigation, localization, and calculation. And there may have been stars that were aligned together like today's southern cross, and these constellations may have also been observed by priests and shamans as they turned their eyes to the heavens, and who viewed these celestial symbols as having heavenly significance.

Stars, of course, are also common spiritual and religious symbols, due in part to their cosmic significance, and the fact that these geometic patterns also activate the limbic system and temporal lobe--structures which serve as a "Transmitter to God." Hence, the "Star of David," the "Star of Bethlehem," and the pentagram.

Yet another factor may be due to the shared commonalty of the limbic system, which contains feature detecting neurons sensitive to geometric stimuli including the sign of the cross and triangles, i.e.pyramids.

The amygdala is able to receive, process and integrate multiple signals from all the sensory modalities simultaneously. The amygdala enables us to hear "sweet sounds," recall "bitter memories," or determine if something is spiritually significant, sexually enticing, or good to eat.

The amygdala enables us to experience the spiritually sublime, is concerned with the most basic animal emotions, and allows us to store emotional and personally significant experiences in memory.

The amygdala also makes it possible for us to reexperience these memories when awake or during the course of a dream in the form of visual, auditory, or religious or spiritual imagery (Bear 1979; d'Aquili and Newberg 1993; Gloor 1986, 1992, 1997; Halgren, 1992).

It is the amygdala which enbles an individual to experience emotions such as love and religious rapture, as well as the ecstasy associated with orgasm, and the dread and terror associated with the unknown. It also appears to generate religious and spiritual significance when presented with the sign of the cross.

The inferior temporal lobe, and thus the amygdala and hippocampus, appears to have been well developed in "archaics," and Neanderthals, comparable, grossly, to the temporal lobes of Upper Paleolithic and present day peoples (Joseph, 1996, 2000a). It is these cerebral structures which have made it possible to experience as well as to attribute spiritual or religious significance to certain actions and geometric signs and stimuli.

Along the neocortical surface of the inferior temporal lobe and the amygdala are dense neuronal fields that contain neurons that fire selectively in response to visual images of faces, hands, eyes, and complex geometric shapes, including crosses (Gross et al. 1972; Hasselmo, Rolls and Baylis, 1989; Morris et al., 1996; Richmond, et al. 1983, 1987; Rolls 1984, 1992). These neurons are sometimes referred to as "feature detectors."

The ability to recognize faces, geometric shapes, and social emotional nuances are dependent on these specialized temporal lobe and amygdala feature-detecting neurons (Gross, et al. 1972; Hasselmo et al. 1989; Morris et al., 1996; Richmond, et al. 1983, 1987; Rolls 1984). Together these structures interact to create complex neural networks that respond selectively to these stimuli, such that, when perceiving a face, star, or a cross the amygdala and temporal lobe become activated.

If the amygdala and overlying temporal lobe were destroyed, the individual would lose the ability to perceive faces or complex geometric stimuli. They would also lose the capacity to feel love or affection, or to recognize family or friends. Isolation would be preferred. They would also cease to experience emotional or spiritual awe in reaction to religious symbols, such as the sign of the cross.

THE AMYGDALA AND SPIRITUAL SYMBOLISM

Neurons in the amygdala and inferior temporal are multimodally responsive, receiving and integrating signals from all sensory association areas simultaneously (Gloor 1986, 1992, 1997; Halgren 1992; Joseph 1992a, 1996; Kling et al., 1987; O'Keefe and Bouma 1969; Rolls 1992; Ursin and Kaada 1960). Because these structures contain feature detectors and subserve almost all aspects of emotion, including religious feeling, it is possible for faces, hands, eyes, and geometric symbols to become infused with, or to stimulate, mystical and religious feeling, incuding for example, the "evil eye." The amygdala located in the right temporal lobe in fact becomes exceedingly excited when it detects that someone is gazing directly at them, or when making threatening gestures with the hands. Hence, not uncommonly divine beings with multiple faces or arms and hands appear in a mystical context.

Moreover, as these nuclei respond selectively to stimuli such as crosses or when being stared at, heightened emotional activity within these limbic nuclei could result in feelings of fear, foreboding, or religious awe which is attributed to objects such as "crosses" or the "evil eye." Crosses, eyes, faces, and related emotions may also be hallucinated if the related feature-detecting neurons are also activated.

Similar explanations could be offered in regard to the spiritual significance attributed to triangles (i.e. pyramids), circles, hands, and eyes. The amygdala and overlying temporal lobe also become activated in response to these perceptual stimuli. In fact, crosses, triangles and circles were etched on Cro-Magnon cave walls over 35,000 years ago (Chauvet et al., 1996), whereas hands, and eyes repeatedly appear in mystical contexts.

However, as to the triangle (which is also the shape of a pyramid), this had long been a sex symbol, and a symbol of fertility, as long ago as the Upper Paleolithic. The triangle is associated with the outer shape of a woman's vagina--the gateway to the womb, the source of life. And, the amygdala is not only responsive to triangles, but it is one of the primary structures responsible for generating sexual arousal, as well as religious and spiritual feelings (Joseph, 1992a).Hence, naked women with their pyramid shaped vaginas not uncommonly appear in a mystical context.

SPIRITS AND THE SOUL

The amygdala enables us to hear "sweet sounds," recall "bitter memories," or determine if something is spiritually significant, sexually enticing, or good to eat. The amygdala also makes it possible for us to store personal, sexual, spiritual, and emotional experiences in memory and to recall and reexperience these memories when awake or during the course of a dream in the form of visual, auditory, or religious or spiritual imagery (Bear 1979; d'Aquili and Newberg 1993; Gloor 1986, 1992, 1997; Halgren, 1992; Joseph, 1982, 1996, 2000a).

The amygdala, in conjunction with the hippocampus, contributes in large part to the production of very sexual as well as bizarre, unusual and fearful mental phenomenon including out-of-body dissociative states, feelings of depersonalization, and hallucinogenic and dream-like recollections involving threatening men, naked women, sexual intercourse, religion, the experience of god, as well as demons and ghosts and pigs walking upright dressed as people.

The amygdala also makes it possible to experience not just the spiritual and religious awe, but all the terror and dread of the unknown. Indeed, the amygdala can generated feelings of hellish, nightmarish fear.

And yet, it is also the amygdala which is responsible for the capacity to transcend the known, this reality. It is also the amygdala which assists in maintaining this reality through the inhibition and filtering of most of the sensory signals bombarding the brain and body. If not for this sensory filtering, a color might have taste and its own particular texture, whereas sounds might provoke smells, warmth, light, colors, tastes, and feelings of weight. Hyperactivation of the amygdala, and overlying temporal lobes removes these sensory filters, and what is concealed is revealed, sometimes in overwhelming confusing majesty.

Neurosurgical patients have reported communing with spirits or receiving profound knowledge from the Hereafter, following depth electrode amygdala stimulation or activation (Penfield and Perot 1963; Subirana and Oller-Daurelia, 1953; Williams 1956). Some have reported hearing even the singing of angels and the voice of demons, the devils, or "God."

THE LIMBIC SYSTEM: SPIRITUALITY AND EMOTION

According to d'Aquili and Newberg (1993) mystical states may be voluntarily or involuntarily induced and are dependent upon the differential stimulation of limbic system nuclei, including the hypothalamus, hippocampus, and amygdala, as well as the right frontal and right temporal lobe. However, it appears that these brain areas differentially contribute to religious and emotional experience.

For example, the hypothalamus is concerned with all rudimentary aspects of emotion, homeostasis such as food and water intake, and controls the hormonal and related aspects of violent behavior and sexual activity. The amygdala also plays a highly significant role in sexual and violent behavior, and, in conjunction with the temporal lobe and hippocampus, enables a human to have religious, spiritual and mystical experiences (Bear 1979; Daly 1958; d'Aquili and Newberg 1993; Horowitz et al. 1968; Mesulam 1981; Penfield and Perot 1963; Schenk, and Bear 1981; Slater & Beard 1963; Subirana & Oller-Daurelia 1953; Trimble 1991; Weingarten, et al. 1977; Williams 1956). These religious experiences, however, may also involve violent behavior or sexual activity, due to limbic involvement.

As we shall see in later chapters, many religious customs and rituals involve violence and sexuality, which in turn is due to the activation of this limbic system transmitter to god.

The amygdala and hypothalamus subserve the capacity to experience feelings of intense sexual arousal, fear or, conversely, euphoria, including an orgasmic feeling of rapture, or the "nirvana" of a heroin "high." This is because the hypothalamus and amygdala are major pleasure centers, and contain opiate-producing neurons and opiate (enkephalin) receptive neurons, thus generating feelings of numbness and a narcotic high. Large concentrations of opiate receptors and enkephalin-producing neurons are located throughout the amygdala (Atweh & Kuhar 1977ab; Uhl et al., 1978).

In response to pain, stress, shock, fear, or terror, the amygdala and other limbic nuclei begin to secrete high levels of opiates which can eventually induce a state of calmness as well as analgesia and euphoria (Joseph, 1998a, 1999a). It is this heroin high that explains why an ox, deer, and other animals will simply give up and lie still while they are devoured and eaten alive. It is this amygala-induced heroin high which also contributes to feelings of religious rapture and the ecstasy associated with life after death and the attainment of Nirvana.

THE AMYGDALA, HIPPOCAMPUS AND HALLUCINATIONS

Whereas the amygdala and hypothalamus interact in regard to pleasure, rage, and sexuality, the amygdala and hippocampus interact to subserve and mediate wholly different aspects of experience, including memory, dreaming, and hallucinations. The hippocampus in particular appears to be responsible for certain types of "hallucinations" such as the visualizations of astral projection or seeing oneself floating above the body (Joseph 1996, 1999b, 2000a). Some patients report not only floating, but of being embraced by a light and taken to a vast realm of fantastic proportions where they are given access to kowledge of the nature of life and death.

Intense activation of the temporal lobe, hippocampus, and amygdala has been reported to give rise to a host of sexual, religious and spiritual experiences; and chronic hyperstimulation can induce an individual to become hyper-religious or to visualize and experience ghosts, demons, angels, and even "God," as well as claim demonic and angelic possession or the sensation of having left their body.

In some instances the individual may come to believe he or she is hearing, seeing, and interacting with gods, angels and demons when in fact they are hallucinating. These false beliefs are accentuated further because they are excessively emotionally and religiously aroused and are experiencing an "enkephalin" high and feelings of rapture or "nirvana."

In many cases, however, the individual is not hallucinating. Rather, their eyes have been opened, and they suddenly see as gods... knowing good and evil.

LSD, LIMBIC SYSTEM FILTERING AND HALLUCINATIONS

The amygdala is capable of processing visual, tactile, auditory, gustatory, olfactory, and emotional stimuli simultaneously. Amygdaloid neurons are multimodally responsive. Normally much of this data is suppressed and filtered so as to prevent the tasting of colors, the visualization of sound, and so on.

Under conditions of hyperactivity, limbic sensory acuity is increased and in many respects what is perceived is not necessarily a hallucination but instead represents the perception of overlapping sensory qualities that are normally filtered out. Colors may be felt and tasted, music may be observed as well as heard, the molecular composition of ceilings, floor and walls may be parted so that one can see through the spaces between where molecules join together. And the pulse of life may be experienced as it ebbs and flows in a leaf one holds between their finger tips.

Consider, for example, a description of someones first LSD "trip."

"It was 1966... Jimi Hendrix was singing about purple haze, and that is exactly what we scored up in Haight Ashbury--mixed by the master himself, Stanley Osley..."

"About half an hour after I'd taken it, I was walking toward the park to meet and trip with my fellow tripsters when I began to notice the incredible clarity and vividness of my surroundings. Colors were brighter, plants seem to sparkle...and I stopped and touched a leaf...I could feel its energy, its life... I could taste it through my fingers...And when I got to the park I was so overwhelmed with the colors, the tastes, the smells, the incredible vividity and clarity that I felt almost overwhelmed and sat down to take it all in..."

"And then I heard a jet somewhere in the distance, and I looked into the sky but couldn't see it but my ears led my eyes to one of the mountains surrounding the valley, and oh my god, I could see right through the mountain. It was like the molecular composition of the mountain was parting into separate molecules. I could see the spaces between the molecules which were all in a frenzy of activity.... it was as if I had achieved X-ray vision, and there were these crystal blue holes--like bubbles--and I could see right through the mountain and I could see the sky on the other side, including the jet. I could see the jet on the other side of the mountain by looking right through the mountain, by looking right through those gaps in the spaces between the molecules which were zipping along in their own unique pattern. And then the jet flew over the top of the mountain and instead of one jet I could see ten, then a hundred, and a kaleidoscope of jets in the sky."

"At first I could see the incredible cellular structure of the skin, and then the molecular structure...the pulsating molecules themselves... and then I could see between the spaces where the molecules joined together... my sight penetrated the skin and I could see the blood vessels, and then my eyes penetrated the blood vessels and I could see inside the blood vessel, I could see the blood platelets and the white corpuscles as they swirled through the vessel--and I kept thinking: How come I never noticed this before? I had forgotten that I had taken LSD."

Hallucinogens, of course, are an age-old means of obtaining access to alternate realities, including the realities of "god." Hallucinogens are said to enable an individual to peer between the space that separate this reality from all other realities, such that what was concealed is suddenly revealed. It is the amygdala, hippocampus, and temporal lobe which are responsible for these complex hallucinations, and it is the amygdala which normally filters much of this information so that it remains hidden. Hence, by hyperactivating these structures, in essence, one is also activating the transmitter to god.

SOULS, SPIRITS, DREAMS, AND POLTERGEISTS

TO KNOW FEAR IS TO KNOW GOD

"Fear the Lord your God." -Deuteronomy 10:12.

Priests, prophets, shamans and many others who encounter "god" or His "angels" not uncommonly experience tremendous fear. Fear is the most common emotion associated with the amygdala (Gloor, 1997; Halgren, 1992; LeDoux, 1996; Williams, 1956), with some patients experiencing horrifying, hellish, and nightmarish fear, sometimes coupled with hellish hallucinations.

Yet others experiences awe and rapture when confronted by the divine. As noted, amygdala hyperactivation is also associated with feelings of extreme joy and ecstasy.

According to d'Aquili and Newberg (1993; p. 194) "a combination of the experience of both fear and exhalation" is "usually termed religious awe." These feeling states are "almost always associated with religious symbols, sacred images, or archetypal symbols" which flow "from the inferior temporal lobe" and which "appear sometimes as monsters or gods". Indeed, angels, demons, and poltergeists may be experienced.

"Cindy", a 22 year old college student, was plagued by demons and ghosts for months until her abnormal right inferior temporal lobe was surgically removed.

Prior to her brain injury, Cindy had never been very religious, and had certainly never seen a ghost; that is, until following her auto accident. She had been thrown over 50 feet through the windshield of her car and suffered a fracture of the right temporal region of the skull and developed a subdural hemotoma, a blood clot, which was pressing on the temporal lobe inducing herniation. Burr holes were drilled into her skull and the clot was surgically evacuated. Although her brain and temporal lobe had been injured, over the following weeks she seemed to quickly recover.

It was several days after her release from the hospital when she was startled while watching television. The arms, legs, hands, feet, and heads of the various actors began protruding from the screen into the living room where she sat.

Cindy said that at first she thought the television was broken and turned it off. But, as she stared back at the blank screen she saw what looked like her dead father staring back at her (which was probably her own reflection). As she backed away, the figure emerged from the television. He beckoned to her, and then behind him ghostly spooks and wraiths began to stream from the picture tube.

Terrified and crying for her mother she raced for the bathroom and locked herself in. Yet, even as she hid within the inner sanctum of the washroom, spirits, sprites and poltergeists streamed from the bathroom mirror and swirled about her. Crying and stumbling, she raced back into the living room and was horrified to see a spirit enter and take possession of her mother. Her mother was transformed before her eyes.

Panicked and terrified, Cindy ran into the street crying for help. A police officer, after investigating the scene, brought her to the local hospital and psychiatry unit. She was medicated and kept there on a 72 hour hold.

Later she decided what she had experienced were ghosts and lost souls of people who had been buried in an old, almost completely forgotten cemetery on the other side of the hill from where she lived. She also thought they were the ghosts of Indians who had been entombed beneath her house as there are numerous Indian burial grounds in the county.

Once she was released from her 72 hour psychiatric hold, she stopped taking her medication, and over the course of the next several weeks, she claimed to see "animal spirits." She reported that fairies would sometimes dance outside her house in the moonlight, and that the "secret souls" of her mother's house plants were watching and observing her and that she could sometimes see filmy, soul-like entities traveling to and fro across the room and between different plants.

DREAMS, ANIMAL SPIRITS AND LOST SOULS

Across time and culture, people have believed that not just humans and animals, but plants and trees were sensitive, sentient, intelligent, and the abode of spirits including the souls of dead ancestors (Campbell 1988; Frazier 1950; Harris,1993; Jung 1964; Malinowski 1948). Before felling a tree, the spirit sometimes had to be conjured forth so as to not harm it (Campbell 1988; Frazier 1950). Be it animal or plant, souls were also believed capable of migrating to new abodes.

Moreover, the ancients believed that the shadows and reflections of others had to be avoided so that one did not come into contact with the soul of a witch, sorcerer, or a demon. It was believed that one's soul could be abducted by demons and witches as well as the recently departed. This is also why in some cultures people turn mirrors to the wall after a death and lay down pictures of the recently departed (Frazier 1950). This insures that living souls are not stolen by the souls of the dead who are leaving this world for the next one.

The belief in the persistence of the soul after death gave rise to ancestor worship in some ancient cultures, including China. Oracle Bones were believed to contain the souls of the dead and were employed for divinatory purposes in ancient China over 4,000 years ago. The earliest Oracle Bones so far discovered, were covered with pictograms including a man with a large ghostly distorted head (Brandon, 1967).

This pictogram also denotes the word kuei, which means, soul. Oracle bones also included characters signifying the words "she, shen, and tsu." "Tsu" means dead ancestor, "she" is a protective fertility deity of the soil, and "shen" are divine beings connotating phallic significance.

The ancient Chinese practiced a religious ritual which was intended to prevent the soul from departing the body at death. The orifices would be stopped up to keep the kuei safely inside the body. So long as the soul remained tethered to the body, the body would not undergo its final fatal disintegration. These beliefs gave rise to the ritual of "calling back of the soul," a ritual also performed for the living as the souls were believed able to wander forth from the body, such as during sleep, exposing the living body to death and extinction (Brandon, 1967).

The ancient Chinese believed that the kuei represented by the yin-soul, was associated with the body since conception. By contrast, a yang-soul was associated with the individual personality and the person's unique mental qualities.

The alternating and competing principles of the yin-soul and the yang-soul are directly related to the concepts of ying and yang. They also gave rise to ancestor worship as the ancient Chinese believed that the life force, the energy associated with the soul, this substance familiale, lay buried beneath the ground as une masse indistincte. "This energy was represented above ground at any given moment, only by the living members of the family, which constituted the individualized portions of that substance familial. It followed, accordingly, that each birth within the family represented the reincarnation of a portion of that subterranean substance familial, while each death meant the return of a part of this individual family substance familial to the masse indistincte in the ground below" (Brandon, 1967, p. 180).

SOULFUL DREAMS

Souls were also believed by ancient humans to wonder about while people sleep and dream (Brandon 1967; Frazier 1950; Harris 1993; Jung 1945, 1964; Malinowkski 1948). That is, among many different cultures and religions the soul is believed to sometimes escape the body via the mouth or nostril during sleep. Moreover, during a dream the soul may wonder away from the body and may engage in certain acts or interact with other souls including those of the dear but long dead and departed.

Sometimes the soul is believed to take on another form, such as a bird, or deer, fox, rabbit, wolf, and so on. The spirit and the soul could also hover about in human-like, ghostly vestiges, at the fringes of reality, the hinterland where day turns into night (Campbell 1988; Frazier 1950; Jung 1964; Malinowski 1954; Wilson 1951). The souls an animal's such as a wolf or eagle, could also leave the body and take on various forms including that of a woman or Man. Not just men but animals too had souls that had to be respected.

DREAMING OF GOD

Priests and prophets as well as the common people, often experienced God as well as animal spirits and the souls of the dead, during the course of a dream (Campbell 1988; Frazier 1950; Jung 1945, 1964; Malinowkski 1954).

Yet, as also noted, these limbic structures also normally acts to inhibit the perception of most of the stimuli impinging on the body. This information is filtered so that one reality is maintained and to prevent the individual from being overwhelmed with competing streams of input. In other words, just as a channel selector on a television or radio permits the select reception of information from a single source (a single reality), these brain structures perform likewise. However, just as there are a multitude of channels, and just as one can change from channel to channel in order to receive a wealth of data, images, sounds, and information from a variety of sources (a variety of realities), likewise, the limbic system can also become tuned to other sources of information which are not normally perceived.

And, once the Doors of Perception are opened, all appears as it is...infinite.

DREAMS, SPIRITS AND REALITY

"I the Lord will make Myself known to him in a vision, and will speak with him in a dream." -Numbers 12.6

When the limbic system becomes hyperactivated it is not at all uncommon for an individual to dream. Dreams, it has been proclaimed, are the royal road to the unconscious (Freud 1900).

It is also via dreams that gods and spirits speak to women and men (Campbell 1988; Jaynes 1976; Jung 1945, 1964). It was via dreams that hunter-gatherers and ancient humans were able to gain access to the domicile of the soul and the spirit world of the hereafter (Frazier 1950; James 1958; Neihardt and Black Elk 1989).

DREAMS AND MULTIPLE REALITIES

Our ancient human ancestors lived in two realities, that of the physical and of the spiritual, both of which were undeniable and experienced by enemies and friends alike (Frazier,1950; Jung, 1945, 1964). One need only spend a night alone in the forest among the trees and the elements to become quickly convinced that one is not alone, but is being watched by various entities both alive and supernatural, animal and spirit, benevolent and unkind.

It is through dreams that human beings came to believe the spiritual world sits at the boundaries of the physical, often where day turns to dusk, the hinterland of the mind where imagination and dreams flourish and grow (Frazier,1950; Jung, 1945, 1964; Malinowkski, 1954); hence the tendency to bury the dead in a sleeping position even 100,000 years ago.

It is also via dreams that humans came to know that spirits and lost souls populated the night. The dream was real and so too were the Gods and demons who thundered and condemned and the ghosts and phantoms that hovered at the edge of night. Although but a dream, like modern humans, our ancient ancestors experienced this through the senses, much as the physical world is experienced. Both were real and were taken seriously.

RIGHT TEMPORAL LOBE HYPERACTIVATION & DREAMING

The amygdala and the neocortex of the temporal lobe are interactionally involved in the production of religious and hallucinatory experiences including dream states (Broughton,1982; Gloor, 1997; Goldstein et al., 1972; Hodoba, 1986; Humphrey & Zangwill 1961; Kerr & Foulkes 1978; Meyer et al., 1987); the right temporal lobe and amygdala in particular (Joseph, 1988a, 1992a).

Similarly, d'Aquili and Newberg (1993) argue that the right hemisphere (and right amygdala) is more involved than the left in the reception and production of religious imagery. This is likely as the right hippocampus and amygdala, and the right hemisphere in general (Broughton,1982; Goldstein et al., 1972; Hodoba,1986; Humphrey & Zangwill 1961; Joseph, 1988, 2000a; Kerr and Foulkes 1978; Meyer, Ishikawa, Hata, and Karacan 1987) also appear to be involved in the production of hallucinations, dream imagery as well as REM during sleep. Indeed, like the limbic system, the right hemisphere is not only associated with dreams, but the unconscious mind (Joseph, 1982, 1988a,b, 1992ab).

Electrophysiologically the right temporal lobe becomes highly active during REM, whereas, conversely, the left temporal region becomes more active during dreamless sleep, i.e., NREM (Goldstein et al. 1972; Hodoba 1986). Similarly, measurements of cerebral blood flow have shown an increase in the right temporal regions during REM sleep. Right temporal lobe blood flow also increases in subjects who upon wakening report visual, hypnogogic, hallucinatory and auditory dreaming (Meyer et al. 1987). Abnormal and enhanced activity in the right temporal and temporal-occipital area will also provoke dreaming and acts to increase the length and amount of dreaming and REM sleep for an atypically long time (Hodoba 1986).

As noted, LSD induces its "hallucinatory" effects by disinhibiting the amygdala. That is, LSD blocks the sensory filtering and perceptual inhibitory activity of a neural transmitter, serotonin. In consequence multi-sensory qualities that are normally suppressed are suddenly perceived such that what was hidden is revealed; sound have color and colors and sounds can be tasted, as the bounds of this reality melt away thus revealing the supernatural reality of the otherside.

Indeed, whereas the right hemisphere is dominant for all aspects of emotion, and is the domain of the more visual and imaginal aspects of the mind, the left hemisphere is dominant for language, math, and the temporal sequential aspects of consciousness. It is the right hemisphere which dreams the dream, and it is the left hemisphere which not only passively observes but which forgets the dream upon waking (Joseph, 1988a). It is the more unconscious realms associated with the right hemisphere which are directly in tune with these alternate realities, such as conveyed through dreams, and it is the left hemisphere which dismisses and rationally explains away these experiences as nonsense.

DAY DREAMS AND FORESEEING THE FUTURE

During dream states we see and experience events which are normally filtered from the conscious mind. We can also gain insight into problems which have plagued us, or gain access to knowledge of events which occurred in the past or which will occur in the future (Joseph, 1988a, 2000a; Jung 1945, 1964)--just as we can think about the future or the past and make certain deductions and predictions.

Consider the day dream. In addition to its images and memories, the fantasy produced also consists of anticipations regarding the future, and in this respect, the day dream could be considered an imaginal means of preparation for various possible realities. Interestingly, daydreams appear to follow the same 90-120 minute cycle that characterize the fluctuation between REM and NREM periods, as well as fluctuations in mental capabilities associated with the right and left hemisphere (Broughton 1982; Kripke and Sonneschein 1973). That is, the cerebral hemisphere tend to oscillate in activity every 90-120 minutes. This cycle corresponds to the REM-NREM cycle and the appearance of day and night dreams, and the right hemisphere also appears to be the source of day dreams.

According to the ancients, day and night dreams both contained important information, not just regarding the past or the world of souls and spirits, but the future. As possible harbingers of the future, the intentions of the gods, and the future of self, friends and family, it has long been believed that dreams should be observed most carefully and could be used to foretell the future (Campbell 1988; Frazier 1950; Freud 1900; Jung 1945, 1964; Malinowkski 1954). It was pharaoh's dream which foretold that seven years of famine would follow seven years of plenty.

In fact, among the ancients, the American Indians, and even the highly cultured Romans, every once in a while someone would have what is called "a big dream." The big dream was of great importance to the whole clan, tribe, city, or nation. Often, the man or woman having the dream would gather the others together and announce it.

THE TRANSMITTER TO GOD

Given that dreams reflect mental activity, it is thus not terribly surprising that dreams may also contain meaningful information that is not otherwise available to the conscious mind. Since the right hemisphere and limbic system which are responsible for dreaming dreams also "speak different languages" and attend to and process unique types of information, this data cannot always be transferred to and understood by the left hemisphere (Joseph, 1986a, 1988a,b; Joseph et al., 1984). From the perspective of the temporal sequential language dependent mind, these impressions remain unconscious.

The conscious mind is often denied information and social-emotoinal nuances that may be unconsciously conveyed by others but which may be perceived within the right hemisphere and limbic system (Joseph, 1982, 1988a, 1992b, 2000a; Joseph et al., 1984). This is because the information attended to and the manner in which this data is analyzed by the limbic system and right hemisphere is so different from that normally received and processed by the left hemisphere.

Nevertheless, sensory and emotional stimuli, which are normally ignored or filtered out by the language-dependent left hemisphere during waking are nevertheless perceived and analyzed by other regions of the brain so that a variety of conclusions may be arrived at, albeit unconsciously; and the same occurs during dream sleep.
