Electric psychotherapy is too dangerous, so later wintermine is introduced as an alternative therapy. However, it lessens the electricity our brains give out, slows down the functioning of our internal organs as well as our physical reflections, causing us to become very sensitive to coldness and feeling strengthless. Since wintermine proves to be very harmful to our bodies, it is not widely used by psychiatrists today, although there are still psychiatrists using this therapy. Free Association is a comparably more 'civilized' therapy: it gathers several patients together to talk about nothing in specific; they can criticize each other or just talk to each other so they could learn to understand other people's thoughts. Psychiatrists on the one side function as doctors, gradually guiding his subjects' behaviors to become normal. This method can sometimes apply to analyze the patient's dreams. Many scientists today are devoted to find out which part of our cerebrum control mental illnesses, so they can apply counteractive medication or therapy to it. But if one looses control over his mind to the point that his brain wavelengths are all mixed up together, various symptoms are resulted from it, like psychosomatic neurosis and neurosis. Psychosomatic neurosis is also called psychosomatic reaction; its syndromes are not so serious but it includes internal organ malfunctions. There is also a Behavioral Therapy that is designed to counteract with behavioral learning problems. If a family has a mentally ill patient living with them, this patient would be just like a bomb has not set the time yet; it is always possible that he would jump out and attack people around him any moment. The family members will be psychologically exhausted sooner or later, or even lead to group craziness in the end! Therefore, the investigation of social psychology has its own importance, because it can indirectly influence the society's peacefulness and order.
