Michael's application of office based Clinical Hypnosis would be predicated on the founder of Psychoanalysis, Prof. Sigmund Freud's first topography (metaphorical mental map) of the human mind; this being conscious, preconscious and unconscious 'provinces' of everyday thinking and relating.  

Although Freud went on to develop what became his Structural Model Of The Mind, it is of note that he incorporated many of his earliest observations and insights into his later work. In this regard, he specifically acknowledges Clinical Hypnosis paving the way for Psychoanalysis to develop (Freud, Standard Works: Volume 12, 1914/1958, p.148) and later wrote: “... we do not forget how much encouragement and theoretical classification we owe to it [hypnosis].” (Freud, Standard Works: Volume 16, 1917/1963, p.462).  It is of further note that Freud continued to use a therapy treatment couch - which he used for Clinical Hypnosis - in his subsequent practice of Psychoanalysis.
