Ooh, parapsychology and the occult. 134.7 itself is unassigned, but it's between 133 (specific topics of parapsychology; including apparitions, divination, demonology, psychics, astrology and, most importantly, quackery/humbugs) and 135 (dreams and mysteries; including esoteric orders obsessed with alchemy and forbidden knowledge). I'm a man of science, but I get a kick out of this stuff. Parapsychology is the study of magic under the assumption that magic is real and inexplicable, but I'm more interested in anomalistic psychology which is the study of magic under the assumption that magic is NOT real and there are mundane explanations for any allegedly supernatural phenomena (IE debunking).
