Why do people dream? At present, the physiological and psychological mechanisms of dreams have not been completely solved scientifically, but two things are very certain: First, external stimuli can cause dreams. For example, some scholars used to pour ice water on sleepers and wake them up with flashes and sounds. The results show that the proportion of these three stimuli programmed into dreams is 42%, 23% and 9% respectively. The second is thinking during the day and dreaming at night. Many scientists who study the content of dreams have found that dreams often attach importance to daytime experiences. From these two conclusions, we can easily find that as a nightmare, there are at least two reasons for its formation:
1. Some undiscovered diseases have occurred in the body. Generally speaking, the occurrence of organic diseases always has certain symptoms. However, in the early stage of the disease, because the stimulus information of the disease is weak, and in the awake state, because other strong stimulus information is quite weak, at this time, the weak stimulus of the disease can cause the excitement of the cerebral cortex, thus causing various morbid horror feelings in dreams.
2. Strong emotional depression during the day. An American psychologist once reported an example: a woman often dreamed that huge waves pushed her to the sea, while others were far away from her. She is always too scared to shout "help". Psychologists know through investigation that this woman has a heavy burden of work and housework, and often feels invincible, but she is unwilling to ask people around her for help. The sinister scene in the dream is a special description of the difficulties in her life. The psychologist told her that as long as she could get rid of the tension and depression in her life, the nightmare would say goodbye to it.
Therefore, in order to get rid of the nightmare, the following three points are worth noting:
1, stay optimistic.
2. Eliminate contradictions and conflicts.
3. Change the thinking of dependence.
Nightmares, also known as nightmares, occur when children scream in their sleep or suddenly sit up from bed and cry for help. At this point, the child's eyes are wide open and his face is red. After a while, he calmed down and went back to sleep.
If the child was forcibly awakened at that time, the awakened child was at a loss and didn't know what had happened. After being reminded by parents, children can recall carefully and say that they just had a nightmare. This situation is a nightmare, which is commonly referred to as "having nightmares."
Nightmares are abnormal manifestations that occur during sleep. Sleep is a manifestation of extensive inhibition of cerebral cortex. When people sleep, although the function of cerebral cortex is inhibited, the biological waves of brain cells continue to be released. No matter how long a person's sleep process is, it can always be divided into two periods: normal sleep period and heterogeneous sleep period. The distribution of brain waves in these two periods is different. During normal sleep, the brain current is a high-amplitude slow wave, but it is found that it discharges during heterogeneous sleep and the nightmare changes during heterogeneous sleep.
Nightmares are related to mental factors, such as excessive excitement, nervousness and fear. Generally, no treatment is needed. When their central nervous system is mature and the excitation and inhibition functions of cerebral cortex are perfect, the nightmare phenomenon will naturally disappear. If you have frequent children, you can take a proper amount of diazepam before going to bed to help you sleep and reduce the occurrence of nightmares.
Why do people dream?
Dreaming is a normal and indispensable physiological and psychological phenomenon of human body. After people fall asleep, a small number of brain cells are still active, which is the basis of dreaming. Why do people dream and what happens if they don't dream?
Scientists have done some experiments to stop people from dreaming. That is to say, when the sleeper has a dream brainwave, he is immediately awakened to stop his dream from continuing, and so on. The results show that deprivation of dreams will lead to a series of physiological abnormalities of human body, such as blood pressure, pulse, body temperature and skin electrical response ability, and the function of autonomic nervous system will be weakened. At the same time, it will also cause a series of adverse psychological reactions, such as anxiety, tension, irritability, perceptual hallucinations, memory disorders, irritability and so on. Obviously, normal dream activity is one of the important factors to ensure the normal vitality of the body.
Because the right hemisphere is dominant when dreaming and the left hemisphere is dominant after awakening, the dynamic balance between nerve regulation and mental activity can be achieved by alternately waking up and dreaming during the 24-hour day and night activities of the body. Therefore, dreams are a way to balance people's psychological world, especially for people's attention, emotions and cognitive activities.
Dreamless sleep is not only of poor quality, but also a sign of brain injury or disease. Recent research results also confirm this view, that is, dreams are the result of the brain's regulatory center balancing various functions of the body, and dreams are the need for the healthy development of the brain and maintaining normal thinking. If the brain's regulatory center is damaged, dreams will not form, or only some incomplete dream fragments will appear. If you sleep for a long time without dreams, it is worth people's vigilance. Of course, if you have nightmares for a long time, it is often a sign of weakness or some diseases.

Analysis of the causes of nightmares, both physical and psychological incentives, physical illness or discomfort, or even incorrect sleeping position, may lead to nightmares.
Psychologically, it may be caused by the usual psychological pressure. The so-called thinking during the day and dreaming at night, the stimulation of external factors has a great influence on people's dreams. Being criticized at school, being beaten at home, being bullied and laughed at by classmates, even hearing or seeing any horrible sounds or scenes, and falling asleep in a depressed state are very likely to have nightmares.
There is nothing wrong with having nightmares occasionally, but if you often have nightmares, especially when you dream of the same terrible scene, you should pay attention to it, take it to psychological counseling in time, and analyze the possible causes of nightmares. Some nightmares can even be traced back to the stimulation that children received in infancy, and then prescribe the right medicine. Long-term nightmares are extremely unfavorable to children's physical and mental health development.
In fact, dreaming is a normal psychological phenomenon that people appear during their sleep. Under normal circumstances, human brain nerve cells are in a state of inhibition during sleep, and this inhibition process is sometimes complete and sometimes incomplete. If it is not completely suppressed, there are still a few nerve cells in the cerebral cortex in an excited state, and people will dream. Because the activities of a few cells when awake lose the control and regulation of the whole cerebral cortex, some fragments of memory become active without restraint, which may show strange dreams different from normal psychological activities. At this time, if nerve cells related to language and movement are also excited, they will not only dream, but also talk in their sleep or sleepwalking.
The latest research abroad shows that people spend about one-third of their lives dreaming. Nightmares are not directly related to good luck, so don't worry. About the content of dreams, it is generally believed that there are mainly: first, thinking every day and dreaming at night. Some people like to watch some thrilling videos or novels. These stimuli form a memory representation, and once you enter a dream, it is easy to dream about it. Secondly, because people sleep badly, such as sleeping on their stomachs or putting their hands on their chests to oppress their hearts, it is easy to have some horrible nightmares. Some people also have nightmares when they are sick, such as headache and fever, bad heart, lack of oxygen or blood supply to the brain. So how can we reduce nightmares?
Reduce bad stimulation. At ordinary times, you should watch more healthy, beneficial, relaxed and happy movies or novels, watch less or try not to watch movies or novels that are easy to form nightmare scenes, and avoid bad stimuli being stored in your memory. It is best not to use your brain too much before going to bed, so as to avoid the excessive excitement of the cerebral cortex and cause dreams.
Pay attention to your body posture when you sleep. Generally speaking, it is better to sleep on the right. When sleeping on your back, your hands and feet are naturally vertical, and the pillow should not be too high. We should correct the bad habit of sleeping on our stomach.
Prevent physical illness. Many experiments show that physiological and pathological stimuli in the human body may be programmed into dreams. There is some slight inflammation in the human body, which is often not felt in the conscious state, and the slight stimulation caused by inflammation may lead to nightmares during sleep. If someone appears in a dream and his throat is pinched, it is later found to be pharyngitis.
Therefore, in order to get rid of the nightmare, the following three points are worth noting:
1, stay optimistic.
2. Eliminate contradictions and conflicts.
3. Change the thinking of dependence.
