I can totally relate to this as well. I've been places with dimethyltryptamine that I can't even begin to describe. Hellish eternities that seemed to last thousands of years, domains lorded over by beings which, with great fun, make you suddenly appear to loose limbs, cast you out into space, control your thoughts, alien abduction, etc.

Its pretty unspeakable and frightening, but at the same time fascinating and mysterious. The weights on the scales are nigh.
