<P> Dreams mainly occur in the rapid - eye movement ( REM ) stage of sleep -- when brain activity is high and resembles that of being awake .

The length of a dream can vary ; they may last for a few seconds , or approximately 20 -- 30 minutes . People are more likely to remember the dream if they are awakened during the REM phase .

Dreams tend to last longer as the night progresses . During a full eight - hour night sleep , most dreams occur in the typical two hours of REM . </P>
