No, I didn’t know about that study, but it supports speculations by Joe Rogan and Rick Strassman, I think, that the DMT trip is similar to dreaming and perhaps to the NDE. The Bardo Thodol is indeed a good example and it reminds me of the Gnostics’ secret formulas about how to escape from the Archons and reunite with the Source.
I vividly recall thinking, when I was high that time, how strange it is that all the elite interpretations of philosophy and religion are about real psychedelic experiences which most people ignore. This seems the esoteric heart of the dichotomy between faith and reason; it’s really about whether you’re in the throes of the altered states or you’re sober. Skepticism is possible only for the “normal,” unaffected brain. But entheogenic faith in the wild supernatural leads to madness and ultimately to the subversion of civilized society.
Thanks for the link.
