For many years people have been arguing over hypnosis. Still, science has yet to explain how it happens. Nobody really knows why a person does what he does when hypnotised. Again as yet we do not understand much how the human mind works.
It is a natural occurrence for humans to be in a trance state. And hypnotherapy simply makes use of this natural occurrence. Many clients coming for help wish to achieve something or eliminate a habit. Hypnotherapy is highly successful in achieving this.
You are in control at all times.
If you wish you can bring yourself out of trance any moment you wish to. However, once we start working clients tend to enjoy the state of relaxation and often wish that they could continue longer with the session.
