The third element is suggestibility. The person becomes more responsive to suggestions given to him or her. Fourth is what he calls “involuntariness.” That means when you come out of hypnosis, you feel subjectively like you haven't done anything, but that something has been done to you. You may recognize that you're being told to lift you arm, for example, but you feel as if it is being lifted by some external force. Which makes sense, since when I reach for a cigarette, especially when I know I don't need it, I’m being governed by similar subconscious impulses.
Although descriptions of psychic disorders date back to antiquity, the practice of psychiatry in its contemporary form only began to take shape in the late 19th and early 20th centuries, when psychiatry split off from neurology as a distinct medical specialty. Modern psychotropic medications first emerged in the 1950s, ushering in an age of “biological psychiatry” wherein mental suffering was medicalized and increasingly understood from the vantage point of neuroscience and related fields.
Although there are different techniques, clinical hypnotherapy is generally performed in a calm, therapeutic environment. The therapist will guide you into a relaxed, focused state and ask you to think about experiences and situations in positive ways that can help you change the way you think and behave. Unlike some dramatic portrayals of hypnosis in movies, books, or on stage, you will not be unconscious, asleep, or in any way out of control of yourself. You will hear the therapist’s suggestions, but it is up to you to decide whether or not to act on them.
