Once, years in the past, I discovered myself in an ice-cold tub with no reminiscence of strolling to the lavatory or working the bathtub. One other time, I terrified my pal by leaving our resort room in the midst of the evening—then pounding on the door, demanding to be let again inside. Each occasions, I awoke in the midst of these weird incidents. I had been sleepwalking.
Sleepwalking, technically referred to as somnambulism, is as fascinating as it’s freaky. It’s a kind of parasomnia, an umbrella time period for uncommon behaviors that happen throughout sleep, akin to evening terrors and “sexsomnia,” when folks have interaction in sexual exercise with out waking up. Ordinary sleepwalking is unusual: a 2016 analysis evaluate estimated that only one.5% of adults had executed it within the earlier yr. However nearly 7% of adults have sleepwalked sooner or later of their lives, in accordance with the identical research.
The nighttime potentialities are various and bizarre. A 2024 research within the Journal of Sleep Analysis showcased a spread of sleepwalkers’ reported experiences, together with waking up bare on a balcony at 5 a.m., crawling into the lounge on all fours, smearing on nearly a whole pot of costly face cream, and filling a bowl of water and putting it by the mattress for a dreamed-up canine.
What makes folks rise from their beds to do all method of weird issues? Dr. Francesca Siclari, writer of that research and a researcher at Netherlands Institute for Neuroscience, says sleepwalking appears to occur when somebody is partially roused from deep slumber, leaving them in a “hybrid state” the place they’re “each asleep and awake,” able to performing some awfully unusual acts they won’t even bear in mind within the morning.

Researchers don’t totally perceive why some folks slip into this limbo state when most individuals don’t. However sleepwalking tends to run in households, suggesting there’s a genetic part. Sure medicines, sleep issues, and different medical situations may make somebody susceptible to sleepwalking, in accordance with the Mayo Clinic.
Children usually tend to sleepwalk than adults, maybe as a result of their brains are nonetheless growing, says Jennifer Martin, a behavioral sleep-medicine specialist and spokesperson for the American Academy of Sleep Drugs. Kids additionally spend extra time every evening within the part of slumber when sleepwalking sometimes happens: the deep, restorative relaxation that comes earlier than speedy eye motion and vivid dreaming, explains Dr. Sanford Auerbach, an affiliate professor of neurology at Boston College Chobanian & Avedisian Faculty of Drugs. Most individuals outgrow sleepwalking by early maturity, however some revert again in periods of stress or extended fatigue, Martin says.
Research help the hyperlink between sleepwalking and sleep deprivation. Siclari says it appears to occur when an over-tired individual lastly falls right into a deep sleep, solely to be disturbed by noise, sound, or movement. It’s exhausting to wake somebody from deep sleep, significantly once they aren’t well-rested, so that they don’t rise totally. However the interruption appears to be sufficient to vary mind exercise, typically leading to exercise much like what’s noticed throughout vivid goals, in accordance with Siclari’s analysis.
Sleepwalking isn’t inherently problematic, Auerbach says. “It’s not a nasty factor in your well being or factor in your well being,” he says. “It’s extra of an attention-grabbing phenomenon” than an actual trigger for concern—though some analysis has discovered that sleepwalkers are extra doubtless than common snoozers to expertise fatigue, daytime sleepiness, and insomnia, suggesting the behavior could typically mess with the standard of sleep.

Extra regarding are the security points that may come up when somebody is up and about. Individuals can journey or fall once they’re half awake, or worse: a affected person of Martin’s as soon as drove a automotive whereas sleeping, and a affected person of Auerbach’s fell off a second-story balcony. “Normally the issues folks do once they’re sleepwalking are a lot less complicated behaviors,” Martin says, “however folks typically do get themselves into bother.”
When obligatory, clinicians typically prescribe small doses of sedative benzodiazepine medicines to discourage sleepwalking, Auerbach says. Stress discount can also be useful, since sleepwalking tends to flare in periods of hysteria, he provides.
Common sleepwalkers must also contemplate taking security precautions, like placing a gate on the prime of their stairs or putting in a safety system that makes noise if the entrance door opens, Martin says. She says it’s additionally price seeing a sleep specialist to rule out different situations, akin to REM conduct dysfunction, which causes folks to behave out their goals and may result in inadvertent self-harm.
Lastly, if you happen to’re the bedfellow of a sleepwalker, you could have heard the parable that you just’re not purported to wake them whereas they’re on the transfer. Martin says waking a somnambulist gained’t hurt them, past some momentary confusion—however the perfect factor you are able to do for a wandering liked one is gently information them again to mattress for some basic horizontal sleep.
