In trance you will be more aware of what is happening inside you - thoughts, images in your head, feelings. The hypnotherapist will ask you to concentrate when and if he needs you to. He may also ask you to describe what is happening in your head, ask you to explore it further or to try changing part of it. Doing this often helps people to get insight into their problems. Each person experiences hypnosis differently.
Most people find trance states to be normal and natural.
However, if they have not been to a reputable hypnotherapist before, some people have fixed ideas about hypnosis and are disappointed to find that it is not as they believed it would be. If people believe they haven't been in the right sort of trance, they can start to mistrust the process and, of course, this limits the results they will get. In fact, too deep a trance is usually ineffective for therapy as the client becomes unresponsive to the techniques of the therapist. The best trance is a focused state of inner awareness - your attention is on what is happening in your mind and what you are feeling, not on your surroundings. Some people are afraid of being stuck in hypnosis if something happened to the hypnotist.
