I dreamed of resting under a tree at night, and suddenly a shadow came out from behind, which startled me and woke me up. I woke myself up with two shouts ... I hope you can help me.

Here we only talk about the causes and prevention of dreams and nightmares from the perspective of human physiological science. We don't discuss superstitious methods to interpret dreams here, because that is mostly nonsense. It is also a coincidence or other reasons, and occasionally there will be a match. People have to dream a lot in their life, and because of different life experiences, the types of dreams they have are different, but although there are differences, there are still some universal laws to follow. For example, when people want something especially at ordinary times, they will realize or lose their dreams of it; When you are particularly afraid of something, you also have dreams related to it. If you are afraid of bad dogs, you can easily have nightmares about being bitten by dogs. When a person has been ill for a long time, it is easy to dream that his condition will get worse or better or be cured when he meets a famous doctor ... All these show that the dreams that people usually have are related to the environmental conditions in which people usually live. That is, as the saying goes, "I think about it day and night, and I dream at night." Therefore, this dream interpretation method has certain scientific basis. As for Zhou Gong's dream interpretation methods, they were not superstitious, but a kind of science, but people at that time could not explain them from a scientific point of view. Another kind of dream interpretation method in The Duke of Zhou is pure superstition, with less essence and more dross, so most of them have no credible value. It doesn't matter if people have nightmares occasionally, but if they often have nightmares, they should be paid enough attention. Let's analyze the causes of nightmares: 1. Great changes have taken place in environmental conditions, such as the pressure of work and life and the new geographical environment (such as going to other places). 2. Significant changes have taken place in interpersonal relationships, such as disagreement with new colleagues and new bosses and betrayal of friends. 3. I met someone who deliberately made things difficult for me and was threatened by others to attack me and retaliate. 4. The family, relatives and friends met with great misfortune, which made them have terrible associations. 5. Timid or superstitious people watch horror movies and listen to ghost stories. 6, physical health problems, physical decline, illness, especially before a serious illness. 7. Changes in sleeping posture and living habits. Countermeasures for the above reasons: 1. Try to handle the relationship between work and life. Although work is important, life is more important, and health is the most important! Don't be overworked, either change jobs or change companies. Or somewhere else. Health first, work second. Whether making friends, doing work or doing business, try to deal with people with good character, and don't make friends and cooperate with people with ulterior motives. 3, do everything possible to prevent and get rid of the environment that is unfavorable to their own safety, so as to reduce unnecessary dangers and troubles (scientists have found that a deer chased by a beast on the non-note continent grassland will dream of the thrilling scene of being chased by a beast during the day, and its limbs will dance wildly). 4. Try not to make corresponding memories and associations for family members, relatives and friends who have suffered great misfortune. Because this is often futile, it will only increase your mental burden and increase your chances of having nightmares. If you are timid or superstitious, try not to watch horror works at ordinary times. Especially before going to bed. 6. When you often dream or have nightmares, you should have a physical examination according to your physical condition, because some serious diseases have symptoms that can make people have nightmares. This is a prediction before the arrival of a serious disease. 7. When lying on the left side, you should pay attention to completely moving your arms and elbows away from the left side, so as to prevent (especially the elbows, which are not needed near the shoulders, because they are far away from the heart area and will not touch the heart, but the elbows are different) from touching the heart area, because it is easy to touch the left side of your body, which is precisely one of the most easily overlooked heart areas. This is of course no problem for healthy people and people without mental stimulation. But for people who are prone to nightmares, this is an important nightmare inducement. When lying on your back, don't put your arms on your chest, especially on your left chest, and don't press and wrap a heavy quilt on your left chest. These are all important! 8. When you are at home, try not to sleep alone in a room too far away from your loved ones. If you are outside, you can live in multiple rooms with your close friends, and don't rent a house in a remote location. You should try to train yourself to turn over and shout when you have nightmares. In the long run, it will form a conditioned reflex to wake up or wake up relatives and friends and let them wake you up. I hope the above suggestions can help you get rid of your nightmare.
