I dreamed that I had a disaster of mass annihilation.

Dreams have nothing to do with bad luck, but are often caused by people's memories during the day, that is, thinking about the day and dreaming at night.

Dreams are formed by unconscious and disorderly links of information in the brain. Some are forgotten by you, and the information on the edge of memory will be called, which is amazing.

But in fact, most dreams are unpredictable. If dreams can foresee reality, and this foresight can be interpreted, and such an able person does exist, then I can say that 99.99% of such an able person will never meet once in his life.

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.

So how can we reduce nightmares?

To reduce the 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, sleeping on the right side is better, so it is necessary to correct the bad habit of sleeping on your stomach. Friends and dreams are a kind of enjoyment, which allows you to experience many things that you can't. I hope I can help you. Sweet dreams!
