Dreams mainly occur in the rapid-eye movement (REM) stage of sleepâwhen brain activity is high and resembles that of being awake. REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However, these dreams tend to be much less vivid or memorable. The length of a dream can vary; they may last for a few seconds, or approximately 20â30 minutes.
Dream lucidity is awareness that you are dreaming. This awareness can range from a faint recognition of the fact to a momentous broadening of perspective. Lucid dreams usually occur while a person is in the middle of a normal dream and suddenly realizes that they are dreaming.old on to this thought as you drift back to sleep, and you may enter a lucid dream. 1  Note that most lucid dreams occur while the person is fully asleep, usually because he notices a bizarre event and realizes he's in a dream. 2  This is just an alternate trigger that starts off about 25% of lucid dreams.
