I know many different styles and techniques of hypnotherapy [direct and indirect hypnosis, regression, parts work, dream work, past life & metaphysical]. My most important technique is Erickson Hypnosis [my doctoral thesis] This is a complex way of using words, stories, rambles and even grammar. It is seeded throughout the other techniques I use.
Again the book on this site lists and explains the different forms of hypnotherapy I use. And again I get your permission to use the technique before I do so.
