"Ever since the late 18th century when Frans Anton Mesmer brought the use of hypnosis (mesmerism) as a therapeutic tool to the attention of the public, therapists have been using it as a powerful tool to help them with suggestion therapy.
If we look back into ancient history, we will find that the trance like state that we call Hypnosis has been used for thousands of years. In fact, from the study of primitive peoples' religious and healing ceremonies there exists the elements essential to place people into a hypnotic state. By rhythmic chanting, monotonous drum beats, together with strained fixations of the eyes, the village shaman or priest is able to induce catalepsy of the body.
The use of suggestion therapy goes back much further than Mesmer. If Mesmer were to be called the Father of Hypnosis, then the great, great ---- grandfather of Hypnosis could arguably be the ancient Egyptian priest, Imhotep. " 1
Imhotep, is considered the the world’s first known physician and suggestion therapy can be traced back over 4000 years to ancient Egypt. The Egyptians used healing sanctuaries to heal people with all sorts of problems, both physical and mental, most of which today would be classed as psychological problems. These healing sanctuaries were called "Sleep or Dream Temples." In these temples, the sick person was put in to a trance like sleep; priests and priestesses then interpreted the person's dreams to gain knowledge about the illnesses and to find a cure for the illnesses."
