Night terrors, also called sleep terrors, can turn an ordinary bedtime into what looks like a deleted scene from a haunted-house movie. A person may suddenly sit up, scream, sweat, breathe fast, stare with wide eyes, or thrash around as if danger is in the room. The confusing part? They are usually not fully awake. Even more confusing? By morning, they often remember little or nothing about it, while everyone else in the house remembers everything very clearly.
Although night terrors can be frightening to witness, they are usually not dangerous by themselves. They are a type of parasomnia, which means an unwanted behavior or experience that happens during sleep. Sleep terrors are most common in children, especially toddlers and preschool-age kids, but adults can have them too. Understanding the symptoms, causes, triggers, and treatment options can make the situation less mysterious and a lot less panic-inducing at 2:13 a.m.
What Are Night Terrors?
Night terrors are episodes of intense fear, confusion, and physical agitation that happen during sleep. Unlike nightmares, which usually occur during rapid eye movement sleep and may be remembered as a scary dream, night terrors usually happen during deep non-REM sleep. This is why the person may look awake but act unreachable, confused, or unaware of their surroundings.
During a sleep terror, the brain is partly awake and partly asleep. That odd in-between state explains why a child or adult may scream, run, kick, cry, or seem terrified without being able to explain what is happening. It is not stubbornness. It is not acting. It is not a dramatic audition for a ghost story podcast. The brain is simply stuck in a strange sleep transition.
Night Terrors vs. Nightmares: What Is the Difference?
Many people use the words “night terror” and “nightmare” as if they are the same thing, but they are different sleep events.
Nightmares
Nightmares are scary dreams. A person usually wakes up fully, can often describe the dream, and may want comfort. Nightmares are more common later in the night when REM sleep is more frequent.
Night Terrors
Night terrors usually happen earlier in the night, often within the first few hours after falling asleep. The person may scream, sweat, breathe quickly, appear terrified, or move around, but they usually cannot be comforted easily and may not recognize people in the room. In the morning, they often have little or no memory of the episode.
A simple way to remember the difference: after a nightmare, the person is scared and awake. During a night terror, everyone else is scared, and the person is still mostly asleep.
Common Symptoms of Night Terrors
Sleep terror symptoms can look intense, especially in children. Common signs include:
- Sudden screaming, shouting, crying, or gasping during sleep
- Sitting upright in bed with a frightened expression
- Rapid breathing or a racing heartbeat
- Sweating, shaking, or flushed skin
- Thrashing, kicking, punching, or pushing away help
- Confusion or glassy-eyed staring
- Difficulty waking fully
- Not responding normally to comfort
- Getting out of bed, walking, or running
- Little or no memory of the episode the next day
Episodes may last only a few seconds, several minutes, or occasionally longer. Once the event passes, the person often settles down and returns to sleep as if nothing happened. Meanwhile, the parent, partner, or roommate may be standing there with a heart rate that deserves its own fitness-tracker badge.
What Causes Night Terrors?
There is not always one clear cause of night terrors. In many cases, they happen because the brain has trouble moving smoothly between sleep stages. Certain factors can increase the chance of an episode, especially when they make deep sleep more intense or disrupt normal sleep patterns.
Sleep Deprivation
Lack of sleep is one of the most common triggers. When a person is overtired, the body may spend more time in deep sleep, where night terrors are more likely to occur. Children who skip naps, stay up too late, or have irregular bedtimes may be more vulnerable.
Stress and Anxiety
Stress does not always politely leave the room at bedtime. Big changes, school pressure, family conflict, work overload, travel, or emotional strain can all disturb sleep. In adults, night terrors may be linked with anxiety, trauma, post-traumatic stress symptoms, or other mental health concerns.
Fever or Illness
Fever, infection, and physical discomfort can disturb sleep and make parasomnias more likely. A child who is sick, congested, or uncomfortable may have more restless sleep and a higher chance of a sleep terror.
Family History
Night terrors and related parasomnias such as sleepwalking can run in families. If parents had sleep terrors or sleepwalking as children, their children may be more likely to experience them too.
Sleep Disorders
Other sleep problems can contribute to night terrors. Obstructive sleep apnea, restless legs syndrome, irregular sleep schedules, and frequent nighttime awakenings can fragment sleep and increase the risk of abnormal arousals.
Medications, Alcohol, and Substances
Some medications or substances can affect sleep architecture. In adults, alcohol use, sleep deprivation, sedatives, and certain medications may play a role. Anyone who notices new night terrors after starting a medication should speak with a healthcare provider before changing or stopping it.
Who Gets Night Terrors?
Night terrors are more common in children than adults. They often appear in early childhood and may fade as the nervous system matures. Many children outgrow them without needing formal treatment.
Adults can experience sleep terrors too, but adult episodes deserve closer attention, especially if they begin suddenly, happen frequently, cause injuries, involve dangerous behavior, or occur with symptoms of anxiety, trauma, substance use, sleep apnea, or other medical concerns.
Are Night Terrors Dangerous?
Night terrors are usually not harmful in themselves. The main risk is injury. A person may jump out of bed, hit furniture, fall down stairs, or accidentally hurt someone nearby while thrashing. The emotional impact on family members can also be significant. Watching someone scream and panic while unreachable is upsetting, even when you know the episode is not usually dangerous.
The goal is not to “snap” the person out of it. In fact, trying to force someone awake can make the confusion worse. The safer approach is to stay calm, protect the person from injury, speak softly, and guide them back to bed if needed.
What To Do During a Night Terror
If someone is having a sleep terror, the best response is calm, boring, and practical. This is not the time for dramatic speeches, bright lights, or a family committee meeting.
- Stay nearby and make sure the person is safe.
- Do not shake, shout at, or force the person to wake up.
- Move sharp, hard, or breakable objects out of the way.
- Block access to stairs, windows, or doors if the person walks.
- Use a soft, quiet voice.
- Wait for the episode to pass.
- Help the person settle back into bed if they allow it.
For children, parents should remember that the child is not doing it on purpose and may not remember it later. A calm caregiver is the best anchor in a weird sleep storm.
How Are Night Terrors Diagnosed?
Many night terrors can be identified from a description of the episode, the person’s age, the timing during the night, and whether the person remembers the event. A healthcare provider may ask about sleep habits, stress, medications, medical history, family history, and safety concerns.
In some cases, a sleep study may be recommended. This is more likely if episodes are unusual, frequent, injurious, begin in adulthood, or may be related to another sleep disorder such as sleep apnea. A provider may also consider whether the episodes could be seizures, panic attacks, nightmares, REM sleep behavior disorder, or another medical condition.
Treatment for Night Terrors
Treatment is not always necessary. If night terrors are rare, mild, and not causing injury or major sleep disruption, reassurance and good sleep habits may be enough. When episodes are frequent, dangerous, or distressing, treatment focuses on reducing triggers and improving sleep stability.
Improve Sleep Hygiene
A consistent sleep schedule is one of the most useful tools. Going to bed and waking up at similar times helps regulate the body’s sleep rhythm. Children may need earlier bedtimes, predictable routines, and enough total sleep for their age. Adults may benefit from reducing late-night screen use, limiting caffeine, and avoiding alcohol close to bedtime.
Reduce Stress Before Bed
A calmer evening routine can lower the risk of sleep disruption. Reading, gentle stretching, quiet music, warm baths, breathing exercises, or a low-drama bedtime ritual may help. The goal is to convince the brain that bedtime is not a board meeting, a horror movie, or a scrolling marathon.
Create a Safer Sleep Environment
Safety changes are especially important if the person walks, runs, or thrashes during episodes. Lock windows, use safety gates near stairs, keep floors clear, move sharp furniture away from the bed, and consider placing the mattress lower to the ground. For children, avoid top bunks if sleep terrors involve movement.
Address Medical or Sleep Problems
If sleep apnea, restless legs syndrome, chronic pain, fever, medication side effects, anxiety, trauma, or another condition is contributing to sleep terrors, treating that underlying issue may reduce episodes. This is especially important for adults with new or worsening symptoms.
Scheduled Awakenings
For children who have predictable night terrors at about the same time each night, scheduled awakenings may help. This method involves gently waking the child about 15 to 30 minutes before the usual episode time, keeping them awake briefly, and then letting them fall back asleep. This should be discussed with a healthcare provider, especially if episodes are severe or persistent.
Therapy and Stress Management
For adults, or for children with significant anxiety or stressful life changes, therapy may help. Cognitive behavioral strategies, trauma-informed care, relaxation training, and family support can be useful when emotional stress is part of the pattern.
Medication
Medication is not the first choice for most children with night terrors. In rare or severe cases, a healthcare provider may consider medication for short-term use, especially if there is risk of injury or serious sleep disruption. Medication decisions should always be personalized and supervised by a qualified clinician.
When To Call a Doctor
Talk with a healthcare provider if night terrors:
- Happen often or become more intense
- Cause injuries or dangerous behavior
- Lead to major daytime sleepiness
- Disrupt the whole household regularly
- Begin for the first time in adulthood
- Occur with snoring, gasping, pauses in breathing, or restless sleep
- Are linked with trauma, anxiety, depression, or substance use
- Look like seizures or involve unusual movements
For children, it is also worth calling a pediatrician if parents are unsure whether the episodes are night terrors, nightmares, seizures, or another sleep problem. Good medical guidance can save everyone a lot of midnight Googling, which is rarely anyone’s finest research hour.
Practical Prevention Tips
Preventing night terrors is not always possible, but reducing triggers can make episodes less frequent. Start with the basics: enough sleep, regular bedtime, a peaceful wind-down routine, and a safe room. Keep a sleep diary for two to three weeks, noting bedtime, wake time, naps, stress, illness, medications, screen time, and when episodes occur. Patterns often appear once they are written down.
For children, avoid letting them become overtired. A slightly earlier bedtime can sometimes work better than complicated solutions. For adults, pay attention to alcohol, sleep deprivation, shift work, and stress. If episodes occur during periods of intense emotional strain, the treatment plan may need to include both sleep care and mental health support.
Living With Night Terrors: Real-Life Experiences and Helpful Lessons
Families who deal with night terrors often describe the first episode as the scariest one. Imagine a five-year-old suddenly sitting straight up in bed, screaming, eyes open but not really seeing anyone. A parent rushes in, asks what is wrong, tries to hug the child, turns on the light, offers water, maybe even starts bargaining with the universe. The child pushes them away, cries harder, then suddenly lies down and falls asleep. The next morning, the child wants cereal and cartoons and has absolutely no memory of the household emergency they created. Parents, however, remember every second.
One common experience is the feeling of helplessness. Night terrors do not respond like ordinary fear. With a nightmare, comfort usually works. A parent can say, “It was just a dream,” offer a hug, and help the child settle. With a sleep terror, comfort may not land because the child is not fully awake. This can make caregivers feel rejected or alarmed. The helpful shift is understanding that the child is not ignoring comfort. Their sleeping brain simply cannot process it normally in that moment.
Another common lesson is that overtiredness is sneaky. Many families notice more night terrors after late nights, skipped naps, vacations, sleepovers, illness, or busy weekends. The child may look energetic at bedtime, but the brain may be running on fumes. In these cases, prevention may be surprisingly ordinary: earlier bedtime, calmer evenings, fewer schedule swings, and less “just one more episode” screen negotiation. The solution may not be glamorous, but neither is standing barefoot in a hallway at midnight wondering if your house is haunted.
Adults with night terrors often describe a different kind of frustration. They may wake their partner, scare family members, or feel embarrassed about something they cannot remember or control. Some adults notice episodes during stressful periods, after drinking alcohol, while traveling, or when sleep is severely disrupted. For them, tracking patterns can be powerful. If sleep terrors cluster around work stress, alcohol, sleep deprivation, or untreated snoring and gasping, those clues can guide meaningful treatment.
Partners and roommates also need support. Being startled awake by screaming or thrashing is stressful. A practical plan can reduce fear: keep the room safe, avoid grabbing the person unless necessary for safety, speak calmly, and discuss the episode the next day without blame. It helps to agree ahead of time on what to do. Midnight is not the ideal moment to invent a safety protocol while half-asleep and emotionally dressed as a raccoon in headlights.
Many families eventually learn that night terrors are often more frightening to watch than they are harmful to the sleeper. That does not mean they should be ignored, especially if they are frequent or dangerous. But it does mean panic can be replaced with preparation. A safe room, a consistent routine, enough sleep, and medical advice when needed can turn a terrifying mystery into a manageable sleep issue.
Conclusion
Night terrors, or sleep terrors, are intense episodes of fear and confusion that happen during sleep, usually during deep non-REM sleep. They are most common in children and often fade with age, but adults can experience them too. Symptoms may include screaming, sweating, rapid breathing, thrashing, sleepwalking, and little or no memory the next day. Common triggers include sleep deprivation, stress, fever, irregular sleep schedules, family history, and other sleep disorders.
The best treatment often begins with simple but powerful steps: protect the sleeper from injury, avoid forcing them awake, improve sleep habits, reduce stress, and look for underlying medical or emotional triggers. When night terrors are frequent, dangerous, or new in adulthood, professional evaluation is important. With the right approach, most people can reduce episodes and bring more peace back to bedtimebecause sleep should not require a crash helmet, a flashlight, and three witnesses.
