How Quickly Can You Start Dreaming After You Fall Asleep?

Most dreaming occurs during the REM (Rapid Eye Movement) stage of sleep, which typically begins about 60 to 90 minutes after you fall asleep. However, this duration can differ from person to person. Some individuals may find themselves in REM sleep as soon as 15 minutes after falling asleep, whereas others could take anywhere from 100 to 120 minutes.
