"Throughout human history, shamans have used psychoactive compounds in order to enter spiritual domains and commune with supernatural entities, ancestral beings and deities. Yet the rise of what we Westerners call rational thought has closed the doors to these transcendental realms, explaining away all such encounters as chemically frazzled sensory processing.

For all its technological triumphs, though, this disenchanted worldview fails to explain many of the mysteries that permeate consciousness and psychedelic experiences. Among these is the remarkably consistent occurrence of “entities” that are reported to appear during DMT trips, and which tend to resemble each other with astonishing homogeneity.

Both online forums and the annals of academic literature are filled with reports of mechanical elves, praying mantis brain surgeons and extra-terrestrial life forms appearing before DMT users. The regularity of these apparitions has even given rise to the theory that alien abduction experiences may be the result of an overproduction of DMT in the brain."
