What's wrong with not dreaming?

This is normal. As long as you sleep well, it is normal to dream or not.

Some people sleep deeply at night, not dreaming, but dreaming but forgetting when they wake up, so this is a state of dreaming without knowing it.

In addition, normal brain activity is very calm, that is, there is no surprise or shock, so that the brain will not be hinted, and it is not easy to dream when the brain works peacefully during natural sleep.

The other is the law of sleep, that is, the body sleeps well and is not easy to dream.

The reason for dreaming of expanding data is:

There are many dreams, and they are chaotic, and they often have nightmares. I feel very tired when I sleep. It is an unhealthy dreaming state, which will affect the rest and relaxation of the brain and the quality of sleep. It needs treatment and intervention. In short, it doesn't matter whether you dream or not as long as you have good sleep quality. Don't worry, relax and sleep.

The cause and purpose of dreams are still inconclusive in academic circles. It is generally believed that dreams are caused by some nerve impulses released by the brain when processing information and consolidating long-term memory (such as dust raised during cleaning or information flow being processed), which are interpreted by conscious brains as bizarre vision and hearing.
