Trance is commonplace. People fall into traces many times without even being aware that it happened. Examples of this are: reaching the destination of a morning commute, but not recalling the passing of familiar landmarks; daydreaming while sitting in a college classroom; or that anxiety-free state achieved just before going to sleep. The difference between these altered states and clinically used hypnotherapy is that a professionally trained person is involved in helping the patient achieve the trance, which can be done in many ways.
People have been pondering and arguing over hypnosis for more than 200 years, but science has yet to fully explain how it actually happens. We see what a person does under hypnosis, but it isn't clear why he or she does it. This puzzle is really a small piece in a much bigger puzzle: how the human mind works. It's unlikely that scientists will arrive at a definitive explanation of the mind in the foreseeable future, so it's a good bet hypnosis will remain something of a mystery as well.
Advertisers have used this knowledge forever. They get our focus and then they pull us in with keywords and authoritative speech that enter the subconscious mind, bypassing our mental filters. Even as you read this, your mind is focused on the words you are reading and you are not fully aware of the world around you. So trance is a very natural state of mind and doesn't feel weird or different from what you often feel every day.
It’s important to remember that depression, along with severe and chronic mental illnesses such as bipolar disorder and schizophrenia, also affect a person’s physical health. Depression is more than just feeling sad or having negative thoughts. It’s a condition where the chemicals in your brain are imbalanced. Hypnotherapy is a complementary therapy, and it shouldn’t be the only therapy a person uses to enhance their mental health.
Surgery/Anesthesiology (In unusual circumstances, hypnosis has been used as the sole anesthetic for surgery, including the removal of the gall bladder, amputation, cesarean section, and hysterectomy. Reasons for using hypnosis as the sole anesthetic may include: situations where chemical anesthesia is contraindicated because of allergies or hyper-sensitivities; when organic problems increase the risk of using chemoanesthesia; and in some conditions where it is ideal for the patient to be able to respond to questions or directives from the surgeon);
In a July 2001 article for Scientific American titled "The Truth and the Hype of Hypnosis", Michael Nash wrote that, "using hypnosis, scientists have temporarily created hallucinations, compulsions, certain types of memory loss, false memories, and delusions in the laboratory so that these phenomena can be studied in a controlled environment."
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.
