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).
