A friend said that she dreamed that her mother went to a familiar boy's house in the class to meet his mother, and she had a very intimate behavior with that boy.

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.
