1. Dreams are the reflection of our real life.
Dreams are inseparable from real life and have a very close relationship with our real life. Sometimes we can't remember what dreams we had last night, but we still have some feelings about them. Although we can't express this feeling, it always haunts us. Sometimes we think these dreams are ridiculous, but they may not really be divorced from the real society, but they are a potential part of our memory. It is possible that these dreams are fragmented and randomly combined.
Second, I think about it every day and dream at night.
Some people also solve problems that cannot be solved in reality through dreams. I heard from a math teacher that he often did his problems very late and then fell asleep unconsciously. Suddenly woke up and immediately continued to finish his unfinished problem, because he found a solution in his dream. At this time, his thoughts still didn't stop. In the dream, he continued to do his math problem.
Third, randomly create different scenes for yourself in your dreams.
Sometimes we feel that some dreams are absurd, and these dreams often subvert our common sense of real life. Possible things are often combined. Sometimes when I think about these dreams, I really feel ridiculous. In fact, sometimes it is also a way of self-hypnosis and narcissism. We created a very pleasant scene for ourselves and put ourselves in this situation. These dreams are all kinds of random video events, intertwined, and it is also possible to choose some of them.
