The stage of sleep called REM, for "rapid eye movement", is the stage during which dreams occur. If you are awakened while in REM sleep, you remember your dream. This is one of the deeper stages of sleep, and is named after the fact that an observer can see the subject's eyeballs moving rapidly about beneath closed eyelids during this state.
The dreams that people have during REM are dreams that are usually illogical and bizarre. If you are awoken during REM you are more likely to remember your dream than if you were awoken during a NREM
REM (Random Eye Movement).
REM sleep
Approximately 80% of dreams occur during REM (Rapid Eye Movement) sleep. REM sleep is characterized by increased brain activity and is often associated with vivid and more memorable dreams. While dreaming can occur in other sleep stages, the most intense and elaborate dreams typically happen during REM.
Most dreams occur during the Rapid Eye Movement (REM) stage of the sleep cycle. Dreams do happen in other stages of the cycle, but those in the REM stage have had more study. See attached link for further information.
Very recent research suggests that dreams that occur during REM sleep tend to be more agitated and troubled than dreams that occur during non-REM sleep. More research is being done to better understand the difference.
