The Ayahuasca thing seems to be a legitimate phenomenon, though. Multiple people, after taking the drug independently and not hearing about it from other people, report the same thing. They have visions of intergalactic lizard people who claim to be the hidden rulers of the universe. To which the shamans counter "... They're lying, of course..." and then explain more of their traditional cosmology. Given that mammals are just a fancy offshoot of reptile, I suppose the drug might be triggering something in our minds. I have no proof, for example, but I suspect a lot of dragon lore might be based on people "remembering" things like Komodo dragons as well as assorted crocodilians. Have I ever mentioned going down into the sacred well that used to house crocodiles at Kom Ombo? It was amazing, and a part of me kept expecting the holy reptiles to still be there for all there have been no crocodiles near that part of the Nile for centuries.
