Hypnosis is a completely natural, pleasant and harmless state. How many times have you been "in your own little world", distracted by something momentarily or simply daydreaming? How many times have you done something automatically while thinking about something else completely, (like driving, eating, or walking for example)? These were occurances of natural trance.  

In stage hypnosis, the "hypnotist" picks people who are already very suggestable (and this would be true for them even without any hypnosis!). Obviously if they volunteer at a stage show, they are already up for the fun of it and have that performer aspect somewhere in their personality. And out of all of the audience these few are the only ones kept on stage by the "hypnotist".

This is because, the truth is, in hypnosis you are fully in control at all times and will only do or say things that you choose or agree to do or say. 

Pure Hypnoanalysis, when used as a theraputic tool, is a gentle relaxation, focussing the mind on pleasant relaxing thoughts. Hypnosis is one of the most effective, quickest and safest tools for treating many psychologial and emotional problems, behaviours and habits. Most emotional or psychological problems and habits are the result of "automatic" responses and behaviours from our subconscious which seem outside of our control. When your mind is relaxed your subconscious is open to positive changes, new habits and thoughts thus making powerful, permanent changes in our lives very quickly. Doing this removes the old problem feelings, behaviours or symptoms.
