What causes dreams

A dream is an involuntary experience that produces imaginary images, sounds, thoughts, or feelings during sleep. Some scientists have shown that dreaming is associated with rapid eye movement sleep, a light state of sleep that occurs late in sleep.

Scientists believe that all people dream, and that they dream at the same frequency during each sleep. If someone says they have no dreams or only one dream when they sleep, it may be because their memory of dreams has disappeared. Others wake up and know they dreamed, but can't remember what it was about.

Some people think that these dream explanations are unreasonable, dream is a kind of mental activity when people sleep, and the mental activity in the dream is the same as the mental activity when people wake up. The bizarre dream of the dream is caused by the illusion of the stimulation of various objective things when the brain is unconscious after sleep.
