Covert hypnosis is a powerful persuasion skill where a hypnotist can influence the subject without him or her knowing about it. Covert hypnosis is slightly different than stage hypnosis - There's no blatant trance that the subject is put in. Through simply pacing and leading the subject with carefully chosen words and language patterns, the subliminal images, emotions and messages the hypnotist wants to convey will simply sink into the subject's subconscious.
