Conversational hypnosis is a phenomenon not too different from indirect hypnosis, as derived from Milton H. Erickson and popularized as "The Milton Model" in style, but the defining feature is that the hypnotized individual subsequently engages in hypnotic phenomena without conscious effort or choice. Covert hypnosis, like "Ericksonian Hypnosis,""operates through covert and subtle means... to reach deeper levels of consciousness than are touched by the surface structure of language."It is the concept that an individual, 'the hypnotist, ' can control another individual's behavior via gaining rapport. During hypnosis, the operator or hypnotist makes suggestions. The subject is intended to not be completely aware, on a conscious level, of the manipulation.
