" Neuroscientist David Comings drew out the larger implications of such hallucinations for the relationship between our rational and spiritual brains:

The psychedelic drugs like DMT often produce a sensation of “contact,” of being in the presence of and interaction with a non-human being. Highly intelligent and sophisticated test subjects who knew these feelings were drug-induced nevertheless insisted the contact had really happened. The temporal lobe-limbic system’s emotional tape recorder sometimes cannot distinguish between externally generated real events and internally generated non-real experience thus providing a system in which the rational brain and the spiritual brain are not necessarily in conflict.
