Hypnosis is an altered state of mind, a state of deep relaxation where you enter a trance. A trance sounds frightening to most people but is a very natural state. We go into a trance many times a day, whilst reading, watching television, day dreaming, even when driving a car.
Anyone can learn hypnosis although as with everything in life some people are better at it than others. There are no special powers needed and there is nothing magical or mystical about it.
Although hypnosis is completely natural it can be very therapeutic by accessing the subconscious and changing negative thoughts into positive ones. And therefore help us with our everyday issues.
In fact most of us use a form of hypnosis and don't realize it. When a child goes to a parent upset the parent will calm him or her talking softly or giving a cuddle. They might even use autosuggestion ( mummy kiss it better).
