Hypnosis is a psychological phenomenon. The relationship between a hypnotist and a participant is based on the participant's cooperation. Without the participant's willingness to cooperate, hypnosis cannot be effectively carried out. When a hypnotist slowly persuades a participant to relax and lose interest in external distractions, it induces a trance state, not sleep.
