The third element is suggestibility. The person becomes more responsive to suggestions given to him or her. Fourth is what he calls “involuntariness.” That means when you come out of hypnosis, you feel subjectively like you haven't done anything, but that something has been done to you. You may recognize that you're being told to lift you arm, for example, but you feel as if it is being lifted by some external force. Which makes sense, since when I reach for a cigarette, especially when I know I don't need it, I’m being governed by similar subconscious impulses.
Trance is commonplace. People fall into traces many times without even being aware that it happened. Examples of this are: reaching the destination of a morning commute, but not recalling the passing of familiar landmarks; daydreaming while sitting in a college classroom; or that anxiety-free state achieved just before going to sleep. The difference between these altered states and clinically used hypnotherapy is that a professionally trained person is involved in helping the patient achieve the trance, which can be done in many ways.
Hypnotherapy is guided hypnosis, or a trance-like state of focus and concentration achieved with the help of a clinical hypnotherapist. This trance-like state is similar to being completely absorbed in a book, movie, music, or even one's own thoughts or meditations. In this state, clients can turn their attention completely inward to find and utilize the natural resources deep within themselves that can help them make changes or regain control in certain areas of their life.
