The theory behind this increased success in altered states is that psi is normally unconscious and when we reduce our sensory input and focus on our mind. When we start to think in primary process (dream type) thoughts, we can more easily connect with the subconscious which is where the psi information is to be found. My research suggests that when we go to sleep at night, our pineal gland, which is traditionally called the third eye or psychic chakra, makes chemicals which create a hallucinogenic state of mind, which we normally call dreaming. These chemicals are virtually identical with the active ingredients in an Amazonian shamanic tea called ayahuasca, which is considered by the shamans to take one out of one’s body, into shamanic flight, in which one can see the future, travel clairvoyantly (in one’s spirit body) and do psychic healing. We make this ayahuasca in our pineal gland every night. The night time is traditionally known to be the psychic time, when witches fly and the fairies dance, and perhaps this is the reason behind our folk lore.
