DMT

Hold on tight! If we ever wanted proof of other dimensions and the reality of otherworldly entities, this is a must-read, assuming one accepts eyewitness accounts of realities way beyond the understanding of modern science. No space ships required just the ability to tap into other levels of consciousness, in this case with N, N-dimethyltryptamine (DMT), the active ingredient in the Amazonian mystic brew ayahuasca.

Strassman's account of his groundbreaking trials left me stunned and wishing others would pick up where he left off. Forget Star Trek and Doctor Who; other realities are much closer to hand.
