If you dream that someone else's house is on fire, the house collapses in half, and someone falls from the house,

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.

So how can we reduce nightmares?

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.
