This is the first book to investigate the world of stage hypnosis as practisced in pubs, clubs, theatres and on television. It uncovers the devastating effects suffered by some of those who have volunteered to take part in shows and discusses the issues with victims who have been damaged physically, psychologically, and socially by the process, or even by the stage hypnotists themselves, some of whom are often incompetent, negligent, ruthless and without any form of training.
