Our most vivid dreams occur during a kind of sleep called "REM." REM stands for "rapid eye movement," because our eyes move back and forth quickly. "Vivid" means bright and lively. Our brain is very active during REM sleep. During the night, we have REM sleep every 90 to 100 minutes. REM periods last as long as 45 minutes. We have more dreams during other phases of sleep, but they are not as vivid.
