A state of sleep caused by methods used by hypnotists or doctors to stimulate people's vision, hearing and touch. This kind of sleep state is different from ordinary sleep, and it is equivalent to a dreamy state or a trance state, which only causes incomplete inhibition of the cerebral cortex.
At this time, the subject's thoughts and energy are concentrated on a certain point, so it is difficult to produce other thoughts and feelings, and it is especially easy to accept hints, that is, certain facts or instructions affirmed in advance, which in turn affects the subject's behavior and feelings, so as to achieve the purpose of adjusting the body's functions, relaxing feelings, and relieving pain.
Extended data:
Hypnosis originated in the18th century, and was originally deceptive, so it was called "Jianghu magic". At that time, Dr. Franz mesmer, a German doctor, invented a magical therapy that could cure all kinds of unexplained strange diseases.
In the dim light and illusory music, he instilled an invisible "hypnotic airflow" into the patient that only he could control. In this way, after hypnosis, the patient will recover.
Although it turned out that Dr. mesmer was not entirely true, he was the first person to discover that thoughts can control and affect the body.
