All Hypnosis is Self-Hypnosis
All hypnosis is self-hypnosis, because the hypnotherapist cannot change anything that is not your personal will, or that will go against your morals. You will only accept suggestions given to you, by the hypnotherapist, that are acceptable to you. The hypnotherapist will only give you suggestions compatible with your desired results.
The given suggestions may, or may not be heard by the client. This all depends on the depth of the trance. Often a client hears partially what is being shared, and often a client drifts off, and does not follow the hypnotherapist at all. It is not important to hear the suggestions with your conscious mind, as your subconscious mind is being addressed.
