This document summarizes hypnosis, describing it as a special psychological state resembling sleep but marked by increased awareness of internal experiences over external reality. It notes that hypnosis involves no physical forces but rather psychologically mediated responses to suggestions. The techniques used to induce hypnosis are described, including establishing rapport, relaxation, and suggestion. The key phenomenon of hypnosis is suggestibility and enhanced responsiveness to stimuli from the hypnotist. Post-hypnotic suggestion, where subjects unknowingly perform instructed acts later, is also discussed. Hypnosis is endorsed as a therapeutic method when used competently in medical contexts but condemned for entertainment due to risk of adverse reactions.
