The hypnotherapist guides you into a state of relaxation and then into hypnosis, a natural state in which your subconscious minds is alert and open to positive suggestions.
While you are in hypnosis, your critical conscious mind is bypassed and the positive suggestions go directly into the subconscious help you to let go of fears and other obstacles or resistances that are holding you back.
Visiting a hypnotherapist is not the same as what you might have seen on TV or in a live performance where a stage hypnotist hypnotizes people in the audience who then do silly things for the entertainment and amusement of the audience.
In private practice, the hypnotherapist works with the client to ensure that he or she is comfortable, understands hypnosis and takes a case history in order to understand the client’s problem/concern that she/he wants to work on.
While you are in hypnosis you are always in control and you can not be made to do anything you do not want to do. You will not reveal any secrets and you can not get stuck in hypnosis.
What you will experience is a deep state of relaxation, not sleep. You may experience heaviness or lightness in your arms or other parts of your body as you go into hypnosis.
This is a pleasant experience and when you emerge from hypnosis generally you will feel refreshed and alert.
