Why do people dream? What is the principle of sleeping and dreaming
Sihainet: as the saying goes, thinking in the day and dreaming in the night. Dream is a very magical and common brain activity of human beings. Just like our movies in the daytime, there are all kinds of dreams. They are fantastic and bizarre. Some people say that dream is a reflection of the real heart. Then why do we dream?
Dream can release mental energy accumulation. All human activities begin with stimulation and end with nerve conduction. The greatest effort of psychological mechanism is to avoid stimulation as much as possible. Psychological energy accumulation caused by internal and external stimulation will lead to venting to a certain extent, but not all psychological stimulation can be released. Dreams are like safety valves, which make subconscious excitement released at night.
Freud's consciousness of man is divided into three parts: 1. Consciousness. It's what we see, what we feel. 2. Subconscious. We say that there is also a large part of the subconscious in the brain. Freud's theory is also called iceberg theory. The iceberg we see in the sea is just a little bit. The ice hidden under the sea is huge. The part you can't see is called the subconscious. 3. Pre consciousness. Between the conscious and the subconscious.
Freud thought that dream is the realization of desire. Specifically speaking, dream is the realization of human's unconscious desire. Some philosophers and psychologists don't agree with this proposition, so far the theory of psychology has not formed a complete unity. But Freud's theory is still very classical, I see so many are not beyond Freud. So I think Freud's view is very classical, very basic, that dreams come from the subconscious.
Freud's view is that all the objects in a dream are symbolic. Every material may have some kind of symbol. Symbolism exists in Chinese traditional culture. For example, totems have different meanings. The totems of wolf, horse and snake have symbolic meanings, which we give them. Maybe in real life, the object has some characteristics, which has some moral expression.
Dreams can also indicate health. Some people dream of eating, finding a toilet, being chased, quarreling with others, fighting, even falling teeth. When they wake up from nightmares, they are often worried and mentally ill. Research shows that if you don't dream about the same content for a long time under human factors, it's likely that some part of your body has pathological changes and sends signals to you. Dreaming of eating and feeling sick may indicate potential diseases of the stomach; dreaming of losing teeth may be related to digestive and respiratory diseases. If a person often has nightmares, it is due to the over excited state of the brain, which may be related to the frequent activity of the brain and the lack of proper rest.
