We know it is hard to sort out all the different claims made by some so-called “hypnosis schools and boards.” Stay away from “distance learning” or correspondence courses that claim to certify you as a clinical hypnotherapist. Hypnosis and hypnotherapy is a healing art based on scientific methods. Only basic hypnotherapy theory can be obtained from the right books or videos. Effectiveness is unlikely without live demonstrations, in-depth and advanced discussion, question and answer opportunities and supervised clinical practice. Just as correspondence courses are inappropriate for counselors, medical doctors and massage therapists, they are wrong for people who want to be effective and successful clinical hypnotherapists.
Some hypnotists view suggestion as a form of communication that is directed primarily to the subject's conscious mind, whereas others view it as a means of communicating with the "unconscious" or "subconscious" mind. These concepts were introduced into hypnotism at the end of the 19th century by Sigmund Freud and Pierre Janet. Sigmund Freud's psychoanalytic theory describes conscious thoughts as being at the surface of the mind and unconscious processes as being deeper in the mind. Braid, Bernheim, and other Victorian pioneers of hypnotism did not refer to the unconscious mind but saw hypnotic suggestions as being addressed to the subject's conscious mind. Indeed, Braid actually defines hypnotism as focused (conscious) attention upon a dominant idea (or suggestion). Different views regarding the nature of the mind have led to different conceptions of suggestion. Hypnotists who believe that responses are mediated primarily by an "unconscious mind", like Milton Erickson, make use of indirect suggestions such as metaphors or stories whose intended meaning may be concealed from the subject's conscious mind. The concept of subliminal suggestion depends upon this view of the mind. By contrast, hypnotists who believe that responses to suggestion are primarily mediated by the conscious mind, such as Theodore Barber and Nicholas Spanos, have tended to make more use of direct verbal suggestions and instructions.
After developing a substantial following — “mesmerism” became “the height of fashion” in late 1780s Paris, writes Marchant — Mesmer became the subject of what was essentially the world’s first clinical trial. King Louis XVI pulled together a team of the world’s top scientists, including Benjamin Franklin, who tested mesmerism and found its capacity to “cure” was, essentially, a placebo effect. “Not a shred of evidence exists for any fluid,” Franklin wrote. “The practice … is the art of increasing the imagination by degrees.”
We experience trance states every day of our lives. When you are day-dreaming, in deep thought, or even watching television, you are in a trance. When you are going to sleep at night, you are in a trance. Trance states are observed in science by brainwave activity. These waves change when a person's brain becomes relaxed. A trance can be light, or very deep like deep sleep.
The British Psychological Society commissioned a working group to survey the evidence and write a formal report on hypnotherapy in 2001. They found, “Enough studies have now accumulated to suggest that the inclusion of hypnotic procedures may be beneficial in the management and treatment of a wide range of conditions and problems encountered in the practice of medicine, psychiatry and psychotherapy.”
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.
