Common Questions about Dreams
Does everyone dream?
Yes. Research shows that we all dream. We have our most vivid dreams during a type of sleep called Rapid Eye Movement (REM) sleep. During REM sleep, the brain is very active. The eyes move quickly back and forth under the lids, and the large muscles of the body are relaxed. REM sleep occurs every 90-100 minutes, three to four times a night, and it lasts longer as the night goes on. ___1___ We dream at other times during the night, too, but those dreams are less vivid.
