Duke Zhou dreamed that a person suddenly disappeared and could not be found.

It means that the previous efforts have finally been recognized by everyone, and people around you have maintained a good impression on you. The above is pure superstition. Dreaming has no substantive significance and function, and there is no scientific basis. Just relax and face life positively.

When people sleep, brain cells also enter a state of relaxation and rest, but some brain cells are not completely rested, and weak stimulation will cause their activities, thus producing dreams.

For example, there is something that makes you particularly excited during the day, and you are still thinking about it before going to bed. When other nerve cells in the brain are at rest and these nerve cells are still excited, you will have a dream with similar content, which is called "thinking day and night".
