People with narcolepsy often report having vivid, bizarre, or disturbing dreams. These dreams can seem very life-like and hard to distinguish from reality. Vivid dreams in narcolepsy may be related to differences in rapid eye movement (REM) sleep. Having narcolepsy, a person can enter REM sleep at sleep onset shortly after falling asleep, making it possible to dream vividly even during a brief nap. Frequent nighttime awakenings are also common in people with narcolepsy, and if the person wakes up during or right after REM sleep, they are more likely to remember dreaming.
Lucid dreaming, or being aware that you’re dreaming during the dream itself, is also more common in those with narcolepsy.
