According to many sources including the National Center for Biotechnology Information (NCBI) which is part of the United States National Library of Medicine and a branch of the National Institutes of Health (NIH), hypnosis is scientifically proven to help relieve both mental challenges and physical pains. Hypnosis can alleviate stress and reduce pain after surgeries, has been shown to relieve anxiety in children in the emergency room, and can be useful for managing pain associated with everything from arthritis to migraines. Hypnosis is non-invasive and gives you a way to control pain or discomfort that might otherwise seem out of your hands. Hypnosis shouldn’t be used as a substitute for medical care, but may be an excellent complementary tool that is best provided by a trained therapist or licensed medical provider. The University of Maryland Medical Center shares many conditions for which hypnosis can be useful:
Braid can be taken to imply, in later writings, that hypnosis is largely a state of heightened suggestibility induced by expectation and focused attention. In particular, Hippolyte Bernheim became known as the leading proponent of the "suggestion theory" of hypnosis, at one point going so far as to declare that there is no hypnotic state, only heightened suggestibility. There is a general consensus that heightened suggestibility is an essential characteristic of hypnosis. In 1933, Clark L. Hull wrote:
The therapy is commonly used as an aid to psychotherapy due to the relaxed nature brought on by the hypnotic state that allows people to explore painful and suppressed feelings and emotions or memories that are often hidden from their conscious minds. This change in consciousness can often lead patients to experience things differently outside of hypnosis, such as criticism at work or home, stage fright, or even pain.

In this state, you are also highly suggestible. That is, when the hypnotist tells you do something, you'll probably embrace the idea completely. This is what makes stage hypnotist shows so entertaining. Normally reserved, sensible adults are suddenly walking around the stage clucking like chickens or singing at the top of their lungs. Fear of embarrassment seems to fly out the window. The subject's sense of safety and morality remain entrenched throughout the experience, however. A hypnotist can't get you to do anything you don't want to do.
In Test 1 Mendelsohn and colleagues found that people in the PHA group (who could experience PHA) forgot more details from the movie than people in the non-PHA group (who could not experience PHA). But in Test 2, after the suggestion was cancelled, this memory loss was reversed. People in the PHA group correctly recognized just as many details from the movie as people in the non-PHA group. Somewhat surprisingly, however, the suggestion to forget was selective in its impact. Although people in the PHA group had difficulty remembering the content of the movie following the forget suggestion, they had no difficulty remembering the context in which they saw the movie.

Findings from randomized controlled trials support the use of various relaxation techniques for treating both acute and chronic pain, although 2 recent systematic reviews suggest that methodologic flaws may compromise the reliability of these findings. Randomized trials have shown hypnosis is valuable for patients with asthma and irritable bowel syndrome, yoga is helpful for patients with asthma, and tai chi helps to reduce falls and fear of falling in elderly people. Evidence from systematic reviews shows hypnosis and relaxation techniques are probably not of general benefit in stopping smoking or substance misuse or in treating hypertension.​hypertension.,​,

That being said- this book will probably be interesting whoever you are. BUT, if you have read and learned all the techniques, this will be a goldmine to you because it is the ONLY book I've read that speaks straight up about hypnosis. GUESS WHAT? Hypnotists don't tell you the truth! It takes a lot of rehearsal and refinement of skill to learn how to control your state and "calibrate" or attune what you're doing to be sure the client is responding well. EVEN then, there will be a fair amount of people you can't get the results you want with. But professionals and teachers don't actually tell you that. They act like what they do works all the time. BS.
"We all need a little help sometimes. My specialties are trauma/PTSD, anxiety, depression, and divorce/custody. I use a combination of The Rewind Technique for phobias/PTSD, Solution Focused Brief Therapy, Clinical Hypnosis and Positive Psychology. Utilizing the latest empirically tested theories in addition to out of the box methods. If what you are doing isn't working; there is ANOTHER WAY."
Whereas the older "depth scales" tried to infer the level of "hypnotic trance" from supposed observable signs such as spontaneous amnesia, most subsequent scales have measured the degree of observed or self-evaluated responsiveness to specific suggestion tests such as direct suggestions of arm rigidity (catalepsy). The Stanford, Harvard, HIP, and most other susceptibility scales convert numbers into an assessment of a person's susceptibility as "high", "medium", or "low". Approximately 80% of the population are medium, 10% are high, and 10% are low. There is some controversy as to whether this is distributed on a "normal" bell-shaped curve or whether it is bi-modal with a small "blip" of people at the high end.[45] Hypnotizability Scores are highly stable over a person's lifetime. Research by Deirdre Barrett has found that there are two distinct types of highly susceptible subjects, which she terms fantasizers and dissociaters. Fantasizers score high on absorption scales, find it easy to block out real-world stimuli without hypnosis, spend much time daydreaming, report imaginary companions as a child, and grew up with parents who encouraged imaginary play. Dissociaters often have a history of childhood abuse or other trauma, learned to escape into numbness, and to forget unpleasant events. Their association to "daydreaming" was often going blank rather than creating vividly recalled fantasies. Both score equally high on formal scales of hypnotic susceptibility.[46][47][48]
“I never expected how much transformation is possible with this work. This hypnotherapy training went far beyond my expectations. The incredible amount of wonderfully presented material and deep wisdom touched my heart on a very deep level. The combination of hypnosis and very profound and effective methods of processing is incredible. To see the profound changes in my classmates and myself is such a gift, I feel deep gratitude for that. To imagine how much positive change will occur in other people due to this work moves my heart.”
In the 1950s, Milton H. Erickson developed a radically different approach to hypnotism, which has subsequently become known as "Ericksonian hypnotherapy" or "Neo-Ericksonian hypnotherapy." Erickson made use of an informal conversational approach with many clients and complex language patterns, and therapeutic strategies. This divergence from tradition led some of his colleagues, including Andre Weitzenhoffer, to dispute whether Erickson was right to label his approach "hypnosis" at all.[10]
