How to recall the name in the dream?

Hello, dreaming is a normal physiological phenomenon. Dreaming is closely related to short deep sleep period, insufficient sleep depth and poor sleep quality. Dreaming more is not an increase in the number of dreams, but an increase in the number of dreams. Dreaming all night is really a feeling of self. It is by no means a functional state that leads to different dreams and cannot accurately reflect objective facts. For example, if you feel very tired, in fact, your body and brain have been fully rested, and you will feel energetic after washing. Don't pay too much attention to this situation. However, if you have insomnia because of many dreams, what you need to pay attention to is that you need to relax and not care too much about dreaming. Between half an hour before going to bed and 1 hour, it is not appropriate to think about problems or read books. You should do proper physical activities (such as walking) to avoid nervous mental activities.

The reason for dreaming

1969, David Fox of emory university did an experiment. When the sleeper is in a heterogeneous sleep state and has strong eye movements, he wakes up the subject and asks him what dream he just had. Then sum up all kinds of situations and draw the following conclusions.

Most of the subjects' dreams are things they care about, such as exams and falling in love. In other cases, such as some people are thirsty, hungry or urinating during sleep, their dreams are basically related to these things. Therefore, these dream stories that connect their own things are meaningless at all. Therefore, some people think that dreams are just an exercise to connect various feelings and events. But someone put forward two hypotheses about dreams through computer models.

Christopher Evans

British psychologist Christopher Evans put forward a hypothesis. He thinks that dreams are like removing a computer terminal and reprogramming it, and then checking it. So sleep is to cut off the input of external signals, and the motion system is in such a rest state. On this basis, dreams test the brain's programs, and then recompile and polish them to train the brain's ability to apply the latest signals to future events.

According to Evans, we humans can be said to be social animals. Therefore, social animals must be divided or classified according to their personality, and this process must be rapid and agile, and dreaming can make this rapid classification exercise.

Francis crick

Another powerful theory also comes from the electronic computer model. The proponent of this theory is francis crick, who is famous for inventing the DNA double helix model.

Crick considered two situations: "mammals have large neocortex" and "mammals and birds have sleep". From the two points of "the cardiac cortex contains crisscross nerve fibers" and "the connection between nerve cells is exciting", we can think that the cerebral cortex is composed of several exciting units or elements. The connection between nerves has three characteristics: the first is divergent afferent; The second is the integrity of strength; The third is polymerization.

The excitation signal enters the local part of this network structure. As the processing feature of this part, as long as there is a signal input, there is a corresponding moderate signal output. When there are signals related to several synapses, there will be interrelated signal outputs.

Therefore, if you ask them to associate their abnormal mental state with this computer model, the following relationship will appear:

1. When the synaptic connection is too much or not smooth, it will produce "fantasy";

2. No matter what signal is input, the same circuit will be excited (forced concept);

3. Even if it is an inappropriate stimulus that generally does not cause a reaction, a reaction (hallucination) will occur.

Crick believes that when an electronic computer makes a mistake, it can cut off the shallow road and check it, but the human brain is different. It can only check shallow roads when sleeping in different phases. During heterogeneous sleep, the brain is isolated from normal input and output, and is stimulated by non-specific stimuli from the brain stem, which is very active. This is the so-called unconscious dream.
