MEDIUM TRANCE
Medium Trance is the next observable phenomenon displayed in the subject during Trance induction. Described as being in a continuum of Levels 12 thru 20, this state of Trance consciousness presents with a variety of clinical manifestations! Initially one may observe, in the subject, the ability to experience
Selective Amnesia at the request of the hypnotist.
Selective Hypnotic Amnesia is not necessarily spontaneous. This phenomenon is facilitated, if within the Trance induction procedure, the subject has received repeated suggestions of drowsiness and sleep {since most people believe they do not remember the contents of dreams when they awaken}.
Hypnotic Amnesia is defined in this context as the temoprary loss of memory associated with an hypnotic experience, rather than loss of memory due to brain injury and the like (which may very well be permanent). Hypnotic amnesia is reversible upon suggestion! Hypnotic amnesia is present when the subject fails to recall either material or events that have been associated with the hypnotic experience, or any other experience that the hypnotist has specifically suggested to be forgotten; and then that same material is recoverable at some later time either through appropriate suggestions or by reinduction of the Hypnotic Trance.
Age Regression / Progression is a product of Time Distortion. This may be accomplished when the hypnotist induces successive amnesias for the current date, week, month and year, prior to suggesting that the patient subjectively return to an earlier period in his life, with the appropriate personality changes, (or to a period in his projected future).
Post-Hypnotic Amnesia occurs when information is learned while in Trance and the result of learning is carried into the waking state, but the process of learning or acquiring the information, and its having been learned while in Trance, is forgotten. This phenomenon is typical of memories related to knowledge obtained in childhood.
Amnesia may be followed by the manifestation of Anesthesia of the feet or hands, or any other area of the body suggested by the hypnotist. Unlike the experience of anesthesia while in Light Trance, the subject actually experiences these phenomena while briefly awake (in the middle of the hypnotic session). Followed by re-introduction into Trance.
Anesthesia (induced Hypnotically), is on a continuum of diminishing bodily sensations with Analgesia. Anesthesia refers to a complete or near complete elimination of all sensation in all or part of the body. Analgesia, on the other hand, refers only to a reduction in the sensation of pain in all or part of the body; allowing the associated sensations of pressure, temperature, position, etc. to continue.
