Hypnosis is an altered state of consciousness. It is not the same as meditation or sleep. A hypnotic trance is a state of focused relaxation and awareness in which your brain waves have slowed from the everyday waking Beta state past the meditative Alpha state into the deeper, slower Theta range.
Entering and maintaining a deep state of hypnotic trance is a skill that can be learned. The more you do it, the better you become at hypnosis.
For a Life-Between-Lives session you must have had at least one previous experience with hypnosis which includes one Past Life Regression. You can do this with me or with another practitioner. (Life-Between-Lives involves a deeper state of trance than usually required for a Past Life Regression.)
Popular ideas about hypnosis include thinking that trance makes people oblivious to their external environment while a movie that they won’t remember unfolds in front of their eyes. This is not usually the case.
