Okay, this anthropologist, Michael Harner, was doing some field work, and it says here that Harner went to the Peruvian Amazon to study the culture of the Conibo Indians. After a year or so he had made little headway in understanding their religious system, when the Conibo told him 'if he really wanted to learn, he had to drink ahayahuasca. Harner accepted, not without fear because the people had warned him that the experience was terrifying. The following evening, under the strict supervision of his indigenous friends, he drank the equivalent of a third of a bottle. After several minutes he found himself flying into a world of true hallucinations. After arriving in a celestial cavern where a supernatural carnival of demons was in full swing, he saw two strange boats floating through the air that combined to form a huge dragon headed prow not unlike that of a Viking ship. On the deck he could make out large numbers of people with the heads of bluejays and the bodies of humans, not unlike the bird-headed gods of ancient Egyptian tomb paintings. After multiple episodes, which would be too long to describe here, Harner became convinced that he was dying. He tried calling out to his Conibo friends for an antidote without managing to pronounce a word. Then he saw that his visions emanated from giant reptilian creatures that resided at the lowest depths of his brain. These creatures began projecting scenes in front of his eyes while informing him that this information was reserved for the dying and the dead.
'First, they showed me the planet Earth as it was aeons ago before there was any life on it. I saw an ocean, barren land, and a bright blue sky. Then black specks dropped from the sky by the hundreds and landed in front of me on the barren landscape. I could see that the specks were actually large, shiny black creatures with stubby pterodactyl-like wings and huge whale-like bodies. They explained to me in a kind of thought language, that they were fleeing from something from out in space. They had come to the planet earth to escape their enemy. The creatures then showed me how they had created life on the planet in order to hide within the multitudinous forms, and thus disguise their presence. Before me, the magnificence of plant and animal creation and speciation and hundreds of millions of years of activity, took place on a scale and with a vividness impossible to describe. I learned that dragon-like creatures were thus inside all forms of life, including man.'
