-Dreams have nothing to do with bad luck.
Many people have this kind of distress: they often have nightmares and even wake up after falling asleep. Because I didn't sleep well, I felt dizzy the next day, which affected my work and study. Some also worry that nightmares will bring bad luck to themselves, causing psychological fear and anxiety.
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.
