Parasomnia: Understanding Sleep Disorders and What You Can Do

When you or someone you know acts out during sleep—walking, screaming, even hitting—it’s not just strange, it’s parasomnia, a group of sleep disorders involving abnormal movements, behaviors, emotions, or perceptions during sleep. Also known as sleep-related behavioral disorders, parasomnia isn’t just tossing and turning—it’s your brain partially awake while your body is still asleep. This isn’t rare. One in five adults has had at least one episode of sleepwalking, night terrors, or acting out dreams. And while it’s often dismissed as "just a phase," untreated parasomnia can lead to injuries, broken relationships, and chronic exhaustion.

There are different types of parasomnia, and they don’t all look the same. sleepwalking, a behavior where a person gets up and moves around while still asleep is common in kids but can persist into adulthood. night terrors, sudden episodes of screaming, flailing, and intense fear during deep sleep often leave the person confused and with no memory the next day. Then there’s REM sleep behavior disorder, when the normal muscle paralysis during dreaming fails, causing people to physically act out vivid dreams—sometimes punching, kicking, or jumping out of bed. These aren’t just quirks. They’re signs your brain’s sleep-wake switches aren’t working right.

What triggers these episodes? Stress, sleep deprivation, certain medications, alcohol, and even other sleep disorders like sleep apnea can make parasomnia worse. Some people have a genetic link—parents with sleepwalking are more likely to have kids who do too. And while most cases aren’t dangerous, some can be. Acting out dreams might lead to falls or injuries. Night terrors can disrupt entire households. The good news? Many cases improve with simple changes: better sleep habits, reducing stress, removing hazards from the bedroom. In more serious cases, doctors may recommend medication or behavioral therapy.

What you’ll find here isn’t theory—it’s real-world guidance from people who’ve lived with these issues or helped treat them. You’ll see how certain drugs can trigger or worsen parasomnia, what to ask your doctor before switching medications, and how to protect yourself and your loved ones at night. There’s no fluff, no guesswork. Just clear, practical info on what’s happening, why it matters, and what steps actually help.
