Hypnosis

Hypnosis is a human condition involving focused attention (the selective attention/selective inattention hypothesis, SASI),[2] reduced peripheral awareness, and an enhanced capacity to respond to suggestion.[3] There are competing theories explaining hypnosis and related phenomena. Altered state theories see hypnosis as an altered state of mind or trance, marked by a level of awareness different from the ordinary state of consciousness.[4][5] In contrast, non-state theories see hypnosis as, variously, a type of placebo effect,[6][7] a redefinition of an interaction with a therapist[8] or a form of imaginative role enactment. https://en.wikipedia.org/wiki/Hypnosis
