Once, years in the past, I discovered myself in an ice-cold bathtub with no reminiscence of strolling to the lavatory or working the bathtub. Another time, I terrified my pal by leaving our lodge room in the midst of the night time—then pounding on the door, demanding to be let again inside. Both occasions, I awoke in the midst of these weird incidents. I had been sleepwalking.
Sleepwalking, technically generally known as somnambulism, is as fascinating as it’s freaky. It’s a sort of parasomnia, an umbrella time period for uncommon behaviors that happen throughout sleep, corresponding to night time terrors and “sexsomnia,” when folks have interaction in sexual exercise with out waking up. Habitual sleepwalking is rare: a 2016 analysis evaluation estimated that just one.5% of adults had executed it within the earlier yr. But nearly 7% of adults have sleepwalked in some unspecified time in the future of their lives, based on the identical examine.
The nighttime prospects are diversified and peculiar. A 2024 examine within the Journal of Sleep Research showcased a variety 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, creator of that examine 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 keep in mind within the morning.

Researchers don’t absolutely perceive why some folks slip into this limbo state when most individuals don’t. But sleepwalking tends to run in households, suggesting there’s a genetic part. Certain medicines, sleep issues, and different medical circumstances may also make somebody liable to sleepwalking, based on the Mayo Clinic.
Kids 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 Medicine. Children additionally spend extra time every night time 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 University Chobanian & Avedisian School of Medicine. Most folks outgrow sleepwalking by early maturity, however some revert again during times of stress or extended fatigue, Martin says.
Studies 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 laborious to wake somebody from deep sleep, significantly after they aren’t well-rested, so that they don’t rise absolutely. But the interruption appears to be sufficient to vary mind exercise, typically leading to exercise much like what’s noticed throughout vivid desires, based on Siclari’s analysis.
Sleepwalking isn’t inherently problematic, Auerbach says. “It’s not a nasty factor to your well being or a very good factor to your well being,” he says. “It’s extra of an fascinating phenomenon” than an actual trigger for concern—though some analysis has discovered that sleepwalkers are extra possible than common snoozers to expertise fatigue, daytime sleepiness, and insomnia, suggesting the behavior might typically mess with the standard of sleep.

More regarding are the security points that may come up when somebody is up and about. People can journey or fall after 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. “Usually the issues folks do after they’re sleepwalking are a lot easier behaviors,” Martin says, “however folks typically do get themselves into hassle.”
When crucial, clinicians typically prescribe small doses of sedative benzodiazepine medicines to discourage sleepwalking, Auerbach says. Stress discount can be useful, since sleepwalking tends to flare during times of tension, he provides.
Regular sleepwalkers must also contemplate taking security precautions, like placing a gate on the high of their stairs or putting in a safety system that makes noise if the entrance door opens, Martin says. She says it’s additionally value seeing a sleep specialist to rule out different circumstances, corresponding to REM conduct dysfunction, which causes folks to behave out their desires and may also result in inadvertent self-harm.
Finally, in the event you’re the bedfellow of a sleepwalker, you might have heard the parable that you simply’re not speculated to wake them whereas they’re on the transfer. Martin says waking a somnambulist gained’t hurt them, past some momentary confusion—however the very best factor you are able to do for a wandering beloved one is gently information them again to mattress for some basic horizontal sleep.
