Let's take such an interesting example. A person immersed in hypnotic sleep is given bitter medicine, say quinoa powder, and is told that it is sugar. And it seems to a person that he really has sweetness in his mouth. Influencing the hypnotized person who is in a warm room, which is very cold, you can cause him to shiver, narrow blood vessels, etc.
No less interesting is another example. The hypnotized person behaves according to his age. Thus, for example, an adult who is impressed by the fact that he is a two or three-year-old child, walks around the room in small, unstable steps, answers questions with a child's babbling: instead of "car" he says "atomobile".
Young people, who are told that they are old people, walk as if with difficulty, their backs bend, their speech resembles an old age.
This property of hypnosis to increase the susceptibility of a person to the images, thoughts, actions, as well as the opportunity to cause profound changes in the activities of his body since ancient times, clergy, as well as all sorts of witches and charlatans to demonstrate the imaginary miracles.
Medically known are many nervous diseases, sometimes very serious and painful (such as hysterical paralysis, mute, deafness, etc.), which often do not succumb to the action of drugs, but are cured by compulsion, the healing word of the doctor. Sometimes, in these cases, it is especially helpful to have a therapeutic suggestion made by a patient who is immersed in hypnotic sleep.
The scientific explanation of hypnosis reveals the essence of other "miracles". Thus, for example, during a session of hypnosis the spectators were always amazed by the detachment of those who were hypnotized from their surroundings, their indifference to the most severe pain, up to burns and wounds. And scientists see an explanation of these phenomena in the fact that in deep hypnosis some parts of the cerebral cortex can be slowed down much more than in a natural sleep, and then a person does not feel pain from the burn, although any pain caused to him during a normal sleep, would immediately awaken him. However, this does not disprove the close relationship between sleep and hypnosis.
The most important argument in favor of the faithfulness of I.P. Pavlov and his followers of the concept of hypnosis as a type of sleep is that the emergence of both these states require essentially the same conditions, namely, everything that contributes to the emergence and development of cortical inhibition acts as a hypnotizing factor. For example, in order to cause hypnotic sleep in a person, it is best to act as weak or moderate, but lasting and uniformly repetitive stimuli, whether it is rhythmic movements, monotonous sounds, concentration of the eye, repetitive words or light strokes of the skin. This explanation sheds light on what has been hidden under the mask of mystery for many millennia and continues to hide under it in some places even now. Science has not only forever dispelled the fog of superstitions and misconceptions around hypnosis, but also made it possible to use it for the benefit of people.
