The reasons for this splitting can be readily understood in terms of a person's ongoing conflicts, without reference to a separate "unconscious mind" lurking somewhere beyond the bounds of everyday awareness. In fact, it is possible to create an artificially induced dissociation in which two or more ego states talk to each other, merely by suggesting it. I would never want to discourage my friends from using such a technique, for it can still be a valuable tool in the practice of hypnotherapy.
I prefer to use the term multiversal meditation instead of the term hypnosis, because it enables me to employ the concepts of modern physics instead of the outdated ansociaations with sleep, which contemporary brain research has now completely disxredited. The brain waves which characterize a state of sleep are totally lacking when a person is simply responding to the expressed or implied suggestion that one is in a state of hyonosis. And the only person who is really able give you scientific, research-based information about the nature and properties of the "unconscious mind" is an anesthetist!
