Adverse events resulting from relaxation techniques are uncommon. Rare reports describe basilar or vertebral artery occlusion after yoga postures that put particular strain on the neck. People with poorly controlled cardiovascular disease should avoid progressive muscle relaxation because abdominal tensing can cause the Valsalva response. Patients with a history of psychosis or epilepsy have reportedly had further acute episodes after deep and prolonged meditation.
The central theoretical disagreement regarding hypnosis is known as the "state versus nonstate" debate. When Braid introduced the concept of hypnotism, he equivocated over the nature of the "state", sometimes describing it as a specific sleep-like neurological state comparable to animal hibernation or yogic meditation, while at other times he emphasised that hypnotism encompasses a number of different stages or states that are an extension of ordinary psychological and physiological processes. Overall, Braid appears to have moved from a more "special state" understanding of hypnotism toward a more complex "nonstate" orientation.
Remember this is real and not a trick. If you choose to use these powerful tools of suggestion you can help people in pain. If they are depressed or stressed, you can make them feel more at ease. You can help someone relax before a public speaking event. It can be therapeutic and help in defeating addictions and bad habits when used with other tools. This is how hypnosis meant to be used. Hypnosis can be used in social situations as long as the person doing the hypnotic induction has the proper training. Don't trust any stranger you meet! Remember: Use these techniques responsibly and only after you have been trained in hypnosis.
Mendelsohn et al.’s study is important because it demonstrates that hypnotic suggestions influence brain activity, not just behavior and experience. Hypnotic effects are real! This fact has been demonstrated clearly in earlier work, for instance, by psychologist David Oakley (University College London) and colleagues, who compared brain activation of genuinely hypnotized people given suggestions for leg paralysis with brain activation of people simply asked to fake hypnosis and paralysis.
As an experienced Hypnotist, I could go on and on about all the different issues that are presented to me by my hypnosis clients. Many times clients have contacted me with problems I have never considered for hypnosis, yet I find that the powerful combination of my extensive hypnotherapy training and experience as a hypnotist provides me with the knowledge and understanding about hypnosis that I need to help them resolve their issues and lead a better and more fullfilling life due to the changes we have been able to achieve during their hypnosis session.
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.
