Duke Zhou, others cry and I laugh.

In fact, I personally think that dreams are usually cut from memento mori, and they don't necessarily mean anything. I personally believe in materialism. Destiny is in your own hands, not in your dreams.

Crying, laughing and even angry expressions in dreams may be closer to the true feelings of dreamers, so crying and laughing in dreams may not be a good thing. Because in real life, people often can't fully express their emotions, and crying, laughing and being angry in dreams can just vent their depression and become the safety valve of emotions in real life.
