I know a lot about psychedilcs, and I wouldn't rule it out. I'm not sure just how forthcoming he's been about his usage patterns, but the fact that he's gone on multiple multi-day ayahuasca retreats, speaks frequently about mysterious friends who are deeply into all sorts of out-there "new age-y"theories and philosophies, and seems to suggest that he uses psilocybin frequently and in fairly large doses all make it sound pretty plausible to me. If he's doing multi-day darkness retreats and multi-day psychedelic experiences, that means he's likely getting way, way, wa-a-a-ay inside his head at times when his mind is pretty malleable, and if (once he gets all the way in there) he's spending a lot of time thinking about the odd theories of his new age friends, there's no telling what the inside of his mind looks like anymore.
