How to judge hypnotic trance depth and is it important?
There are as many methods of judging hypnotic trance depth, as there are practitioners of hypnosis. At one time only three levels of trance depth were considered to be important — light, medium, and deep. This is inadequate because a greater degree of differentiation is necessary to accomplish all the current applications for hypnosis, such as dental work, surgery, child birth and age regression. We divide trance depth into two general divisions. Yhe first three stages are Mnesic, or memory retaining. The second three stages are Amnesic, or the forgetting stages. This is what we call temporary selective amnesia. Upon awakening and with proper suggestions, you do not remember what transpired under hypnosis.
