The causes of sleep paralysis can include disrupted sleep schedules, stress, narcolepsy, and genetic factors
. There may also be a link between sleep paralysis and vivid nightmares or lucid dreaming, although further research is necessary to investigate these correlations
. Additionally, sleep paralysis can be associated with other factors such as high levels of stress, post-traumatic stress disorder, panic disorder, jet lag, chronic pain, depression, and alcohol use
