Sleepwalking episodes typically last just a few minutes and most often occur during the first third of the night, within deep non-REM sleep. Most people don't remember the episode the next day.
While occasional sleepwalking is often harmless, frequent or intense episodes may signal an underlying issue such as stress, sleep deprivation, or a sleep disorder. If sleepwalking is disrupting your rest or causing safety concerns, it's worth investigating further. Take a free, instant, online symptom check to better understand what may be causing your episodes and get clear guidance on next steps.
