A hypnotist is someone who guides people into a focused, relaxed mental state called hypnosis, where the person becomes highly receptive to suggestions. During hypnosis, you remain aware and in control, but your mind becomes so absorbed in the hypnotist's words that everyday distractions fade away. It's similar to being so engrossed in a book that you don't hear someone calling your name, except a hypnotist deliberately creates this state.

Stage hypnotists perform shows where volunteers appear to do silly things like clucking like chickens or forgetting their own names. While entertaining, this theatrical hypnosis only works because volunteers want to participate and play along. Medical hypnotists, called hypnotherapists, use hypnosis more seriously to help people overcome fears, break bad habits, or manage pain. Some dentists use hypnosis to help anxious patients relax during procedures.

Hypnosis isn't mind control or magic. A hypnotist can't make you do anything against your will or values, and you can't get “stuck” in hypnosis. Think of a hypnotist as a guide who helps your mind reach a state of deep concentration. The hypnotist provides suggestions, but your brain decides whether to accept them. The technique works through cooperation between the hypnotist and the person being hypnotized, not through mysterious powers.
