Why do people have all kinds of dreams when they sleep at night?

Dreaming generally refers to various fantasies that occur during your sleep due to some external factors, or some local activities in the body that stimulate the brain.

The first reason for dreaming may be physical, the second may be psychological, and the third may be physiological. This kind of dream is different for everyone. If something different happens to you every day, then this kind of imagination will appear in your mind, and dreams will appear. Or if your body has poor sleep quality and your mind is more active, you will also have dreams at this time.
