A state of relaxation and concentration at one with a state of heightened awareness induced by suggestion. It is a non-addictive power for good and is a natural manifestation of the mind at work.
Most people are surprised to remember all that has happened during the therapy.
No, you are simply extremely relaxed. Hypnosis is a proven therapeutic aid. Simple problems, such as smoking, nail biting, slimming, pre-test nerves etc usually require a single session and the success rate is surprisingly high. The more deep-rooted nervous disorders require 'analytical' rather than 'suggestion' therapy which usually consists of 8 weekly sessions. In fact you would be shocked out of the hypnotic state immediately any such action was suggested to you.
