Automatic Writing can be used very effectivley as a form of therapy - possibly under hypnosis. I agree that the 'channelling spirits' part sounds a bit sinister and I wouldn't try it myself like that, but it does have more practical uses too. It basically works by, when in a state of deep relaxation or trance, you allow your hand to draw or write answers to a question that might be bothering you and little tiny, subconscious, muscle movements in your hand wiggle the pen about and make a scribble - which may or may not be readable but can often, with help, be deciphered to give an answer.
