Hypnosis

Hypnosis is a natural psychological process in which critical thinking faculties of the mind are bypassed and a type of selective thinking and perception is established. Although some individuals experience an increase in suggestibility and subjective feelings of an "altered state of consciousness", this is not true for everyone. In fact, some supposed hypnotic indicators and subjective changes can be achieved without relaxation or a lengthy induction by means of simple suggestion or waking hypnosis, a fact that increases the controversy and misunderstandings around hypnosis and the hypnotic state.
