Brief Summary

Mystical experience is described as an experience that is unique to everyone, potentially transformative and leaving a mark for many years or even a lifetime. It is characterized by: a loss of self/ego, being with the whole/nature/universe, transcendence, a loss of spatio-temporal reference points, ineffability, peace and joy, a sacred character, and a noetic quality. The mystical experience is one that occurs in the context of non-ordinary states of consciousness such as meditation and the consumption of so-called psychedelic drugs, for example. It would seem, in fact, to correspond to the transformative mechanism of the psychedelic experience. The goal ofthis study is to investigate the possibility of a mystical experience through hypnosis.
