Hypnosis is considered as a psychological technique. In some public hypnotic performances, people see some hypnotized people doing everything the hypnotist said without realizing it, such as imitating playing without playing the piano, being burned by cold water, and being able to stand on their back and endure people's trampling without feeling pain. You may be scalded by cold water during hypnosis. Why are hypnotized people scalded by cold water? This problem should be explained from a scientific point of view. People are often used to thinking that people's feelings are uncontrollable. Usually, we can't tell cold from heat. The point is that hypnosis is an abnormal situation. Because the human body has no specific feelings about pain and temperature, this feeling is not single, and it often becomes less objective in comparison. Not only that, the generation of pain and warmth is also very complicated, which is not only influenced by receptors, but also by cognitive processing of the brain. Experiments show that if the subject holds two rubber hoses, one is warm water and the other is ice water, the subject will feel that the ice water is hot. In other words, the contrast of temperature will cause strange and objective pain, but this feeling is real, even if it is not hypnosis, it is the same in reality. It is only when we consciously realize that it is ice water that we will take the initiative to call that feeling cold. Can you bear more weight without fear of pain during hypnosis? Not afraid of pain when hypnotizing, this experience is reflected in many hypnotic performances. Because most people who can be hypnotized are easy to accept the hypnotist's psychological hints (people who are not easy to be hypnotized are generally not easy to succeed and will not lose consciousness during hypnosis), hypnotized people are always used to playing a role with the hypnotist, so if the hypnotist tells you that it hurts, you will feel very painful, and if he tells you that it doesn't hurt, you will feel fine. To be honest, this phenomenon is not uncommon in life. The stomachache when you are busy writing a paper and the stomachache when you are idle is always more severe.

A hypnotized person told his hypnotized experience. After hypnosis, the narrator has two chairs on his head and feet, and his body is suspended. An adult man stood on the commentator without any pain.
