You certainly will not be asleep or unconscious. If you were asleep, you would not be able to have a dialogue with your hypnotist. While under hypnosis, you are in a very relaxed and pleasant state.
Hypnosis is safe when a competent and qualified hypnotist practices it.
Hypnosis is a term derived from the Greek word for sleep. Hypnosis is very relaxing. However, you never lose awareness during hypnosis. When you are hypnotized, you continue to be aware of your surroundings. Everyone has experienced hypnosis.
