You've seen it all. It's really hypnosis and being used again. Those so-called hypnotists take advantage of the patient's eagerness to go to the hospital to cheat, which is really outrageous. Hypnosis can indeed be used to treat diseases, but it mainly plays an auxiliary role, such as helping sleep, hypnosis to lose weight, quitting smoking and so on. All propaganda that describes hypnosis as too magical should be careful of cheating. I once took part in hypnosis training. My teacher is a prestigious predecessor in hypnosis. He pointed out many times that the main function of hypnosis is healing, both physically and mentally. At that time, I also experienced some hypnosis, which gave me the feeling that my mind was very relaxed and as impressive as taking a bath.
