Starting from these theories, we can learn from what we usually call "thinking day and night".
But it doesn't mean that dreams at night have something to do with what you think during the day. After all, most of the brain is at rest during sleep, so dreams are usually pieced together by some memento mori. In this case, there will be many bizarre plots, which is not surprising.
Your dream may be caused by a combination of different stimuli and accidents, regardless of age.
As for the explanation in many cases, it may be related to the personal thinking mode, because in general, it is not easy for people to remember their dreams because the information in the dreams has not been processed by the brain; It is generally believed that when you wake up in a dream, it is easy to remember the dream.
On the other hand, your dream is against the so-called social ethics, so you will process the relevant information in your brain, which will easily lead to the recurrence of the plot in your next sleep consciousness. Repeat this way, and you will have many dreams.
In this case, generally don't care too much.
