Carl Jung believed that the subconscious had two parts, one containing an individuals darkest fears, things that go bump in the night , etc.. and another that he called 'the collective subconscious' - which includes all information that has ever existed, and is the one that makes 'psychic' stuff possible.
Further, the old hypnotists noted that during hypnosis, during trance, a few of their subjects were able to demonstrate psi activity.
So I would dun again that Hypnosis is what is works in Scn... well other than their lawyers who are always working...
You have any interesting URLs re psi activity demonstrated during hypnosis?
Here is one,but there are 34 million choices on a google of "psi activity hypnosis"!
I think more likely that hypnosis and recall have something in common.
Recalling incidents can require strong concentration.
