Clinical Hypnotherapy allows the client to enter a relaxed state of mind that is more receptive to outside influences and suggestions thus allowing the way they think or behave to change. It does not mean running around pretending to be a chicken! That would be stage hypnosis a totally separate activity entirely.
The Clinical Hypnotherapist uses various techniques to relax the client and help them reach a trance like state where unwanted negative habits, patterns of behaviour and beliefs can be removed and where desired positive attributes can be introduced; confidence, positive self esteem, the will to succeed. All this is done by communicating with the subconscious mind rather than the conscious mind.
