Hypnosis is not a sleep-state, although the body and mind are both in a relaxed state. During hypnosis the subconscious mind is more awake, while the conscious mind is still functional, but the ‘volume’ of the critical faculty has been turned down. The ‘critical faculty’ is the part of the conscious mind which tells us for example that something is ‘warm or cold’ or the earth is ‘flat or round’. In order to do any age-regression work, the ‘critical faculty’ must be by-passed.
While in the hypnotic state, the person is thus not ‘under’ or unconscious, but fully aware of everything that is going on around him, and remembers what happened during the session.
