Dreaming about the future, and it happened, more and more clear, you can know what will happen in advance, but you can't change it.

From a scientific point of view, dreaming is an imaginary scene. When animals are asleep, some brain cells will be active for a while. Some people say that they had a dream all night, but when you think about it, there are only one or two scenes that are really clear during the whole dreaming process. In fact, the whole dreaming process is the continuation and expansion of people's imagination of the dream scene when they are awake or half asleep. Then why do we think that dreams can predict something? That's because according to the normal law, sleep state is the process of brain cells resting. When resting, people still feel that some situations are not in line with the normal laws. Humans always like to classify what they think does not conform to their cognitive laws into the field of theology. After all, the end of science is theology. For example, dreaming of fish indicates something, seeing hoodoo indicates something, hail indicates something, earthquake indicates something, and so on.
