Parasomnias During the COVID-19 Pandemic

Parasomnias are undesirable physical events or experiences that occur during entry into sleep, within sleep, or during arousal from sleep. Parasomnias may occur during non-rapid eye movement sleep (NREM), rapid eye movement sleep (REM), or during transitions to and from sleep.1 Many parasomnias are the result of mixed states with the concomitant presence of multiple statedetermining biomarkers. According to the recent view of sleep as a "complex local phenomenon", different states of consciousness, such as wakefulness, NREM sleep and REM sleep, can concurrently result in these "altered", but not necessarily pathologic,2 states.
