I dreamed of an alien bug, and then I went to cut it with a knife. The bug is a bit like the big bug in [Men in Black] and a bit like an earthworm, so I brought a kitchen knife.

Dreams have nothing to do with bad luck, and strange answers make dreams more mysterious. Scientific research has proved that dreams are caused by the release of memories during sleep at night, and are formed by the unconscious disorderly link of information in the brain. It's amazing that some information on the edge of memory will be recalled long after you forget it.

But in fact, most dreams are unpredictable. If dreams can foresee reality, and this kind of foresight can be interpreted, and such talented people do exist, then the probability of realization is very low, and 99.99% people will never encounter such a situation in their lifetime.

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 memory fragments in daily activities during the day will naturally become active and 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.
