There are four main ways that we can enter hypnosis.
Each of us enters a state of hypnosis when we wake each morning and when we go to sleep at night. The transition period between sleep and awake where we are not quite fully conscious is a hypnotic trance state, this is what is referred to as relaxation hypnosis.
Complete focus of the conscious mind also induces a hypnotic trance state. For example when we are reading a book and become unaware of our surroundings as we are so wrapped up in the story we are reading.
Shock hypnosis is where something takes us by surprise, and in this instance we go into a hypnotic trance. Showmen hypnotists use these methods to induce a hypnotic trance.
Confusion, this is where we use distraction to confuse the logical mind and whilst this is going on we can get through and talk to the subconscious mind.
In clinical hypnosis we will concentrate on relaxation and Focus in order to induce hypnotic trance.
