hypnosis Cultural  

1. Placing persons in a drowsy, sleeplike state in which they allegedly become vulnerable to the suggestions made by the hypnotist. Hypnosis may also be used to tap into the unconscious and is often characterized by vivid recall of memories and fantasies. These properties make hypnosis a useful tool in psychotherapy. Hypnosis also has sinister implications, for subjects may be manipulated to perform embarrassing actions or be susceptible to carrying out the hypnotist's commands after the hypnosis session (posthypnotic suggestion).

Etymology

Origin of hypnosis

First recorded in 1875–80; hypn(otic) + -osis

Explanation

Hypnosis is a trance-like state induced by a hypnotist in which the subject becomes highly open to suggestions by others. In movies, hypnosis usually starts with the phrase, "You are feeling very sleepy..." Thanks to a million bad TV shows and stage hypnotists — "look into my eyes, you are feeling sleepy..." — we tend to think of hypnosis as making its unfortunate subjects think they're birds and run around flapping their arms for our amusement. In fact, modern day hypnosis is more commonly used by therapists to help people modify undesirable behaviors such as smoking or anxiety. Helpful, if not as much fun.
