Have you ever noticed how you might be trying to remember something and the
harder you try to remember the more difficult it becomes until you just give
up trying? And later, when you thought you'd forgotten all about trying to remember,
the information you wanted just popped into your mind?
Well, of course we know that the information was there the whole of the time
but you were experiencing what Emile Coue termed as the "Law of Reversed
Effect"
And of course we all know how the mind can wander when we are feeling relaxed
and all sorts of memories can flow up into conscious awareness.
So, using hypnosis to improve your memory makes sense. In fact, many accelerated
learning programs such as speed reading to develop a photographic memory actually
use a state of altered consciousness similar to hypnosis (although they don't
usually tell you so), instead they may talk about Alpha and Theta states.
