The word “hypnosis” is derived from the Greek hypnos meaning “sleep.” Actually, you’re not asleep when hypnotized, but rather are in a trancelike state of restful alertness. This is accompanied by an extreme openness and receptivity to suggestion. Hypnotherapy is the use of hypnosis for self-improvement and/or healing. All hynotherapy employs hypnosis, but not all hypnosis is hypnotherapy.
