Can hypnosis causes irreparable harm?
An emphatic NO! Hypnosis, per se, is no more dangerous than natural sleep and there is no evident that it can weaken the will, damage the nervous system or result in any adverse reactions. The hypnotic relationship is used primarily to communicate directly with the subconscious mind, resulting in suggestions being acted upon because they are perceived more fully (assuming the suggestions are in accord with the subject’s wishes). An incontrovertible fact is that no one has ever died from hypnosis and, actually, there is no modality less dangerous than hypnotism. There could be one danger, and this is not in hypnosis itself, but in unqualified therapy, which might keep someone from seeking needed medical help. This is why the ethics of our professional associations require medical approval before accepting a case.
