There is a massive difference between clinical hypnosis used in a private office setting and stage hypnosis performed in a club or at a party.
Stage hypnosis is a type of amusement that seeks to amuse an audience by directing participants that are willing to participate in stunts or occasionally foolish behaviour under the focus of a stage hypnotist.
By comparison, clinical hypnosis is a highly successful, commonly studied and widely practiced type of short-duration practice for treating a huge variety of mental and physical issues. It's a private, one on one, collaborative and interactive healing procedure that occurs in a secure, comfortable, managed clinical setting. During each session, the client or patient enters a natural state of focused relaxation, by choice, with a set of specific goals depending on the focus of the treatment session. Through the use of techniques and numerous hypnotic suggestions, as well as directed conversation, the patient learns to go beyond limits and their fears to accomplish their targets that are particular for long-term self improvement.
Being hypnotised is not really like what you often see on TV, it's really just a state where your mind and body become serene and peaceful, achieving heightened self awareness and inward focus, creativity that is expanded and imagination that is increased. This really is a great state for creating positive change. It's not like being out of control, it's actually being in complete control of your thoughts, feelings and emotions and it's intensely powerful.
The mind can't keep contradictory states concurrently so by using hypnotherapy as a tool to manipulate your mind to be in a better, more receptive state your motivation, subconscious and actions can be changed. The truth is that most of the time it is extremely hard to change, we are simply not wired to be receptive to change very easily. Hypnotherapy and NLP allows us to switch your mind into a mode where it's ready to be changed.
Ideas given to it take deeper root and develop more completely and much more rapidly, creating changes, new feelings, attitudes, desires, and new ideas that replace the old ones. What bubbles up to consciousness is a powerful inspirational drive to accomplish your particular goals through consistent, positive actions.
