Night Terrors vs. Nightmares: What’s Waking Your Child Up?
A scream from your child’s bedroom can bring you out of sleep in an instant. But what happens next can be confusing: your child may reach for you and describe a scary dream, or they may seem terrified without recognizing that you’re there.
The main difference is whether your child is truly awake. After a nightmare, children usually wake up, accept comfort, and may remember the dream. During a night terror, a child remains partly asleep, may be difficult to comfort, and usually has no memory of the episode the next morning.
Both can happen during childhood. Understanding the difference can help you respond calmly, keep your child safe, and recognize when a nighttime disturbance deserves a conversation with your pediatrician.
Night Terrors vs. Nightmares in Children: How Can You Tell?
No single sign tells the whole story, but these patterns can help you understand what you’re seeing.
Nightmares: A frightening dream your child wakes from
Nightmares happen during rapid eye movement, or REM, sleep—the stage associated with vivid dreaming. They’re more likely later in the night, when children spend more time in REM sleep.
After a nightmare, your child may:
Wake up crying or call for you.
Recognize you and respond to reassurance.
Describe a frightening dream, depending on their age.
Worry about going back to sleep.
Remember the dream the next morning.
A preschooler may only say something was “scary.” A school-age child might describe a detailed dream and ask you to check the room or stay nearby.
Night terrors: Looking awake while still partly asleep
Night terrors, also called sleep terrors, happen during a partial awakening from deep non-REM sleep. They usually occur in the first part of the night, often within the first few hours after falling asleep.
During a night terror, your child may:
Suddenly scream, sit up, or thrash around.
Have open eyes but seem to look through you.
Sweat, breathe quickly, or have a racing heartbeat.
Push you away or seem more upset when you try to comfort them.
Settle back into sleep without fully waking.
Have little or no memory of the episode afterward.
Episodes often last a few minutes, though some last longer. Night terrors are more common in younger children, and many children outgrow them. Although they can look alarming, a typical episode usually isn’t harmful unless the child gets hurt while moving around.
Why Do Nightmares and Night Terrors Happen?
Occasional nightmares can follow an upsetting experience, a frightening video, or an ordinary childhood worry. Changes at school or home may also show up in dreams. Sometimes there’s no obvious explanation.
Night terrors are linked to the way a child moves between sleep stages. Being overtired, having an irregular sleep schedule, being ill, or experiencing stress can make episodes more likely. Night terrors and sleepwalking can also run in families.
Neither event means your child is misbehaving. A child having a night terror isn’t deliberately ignoring you, and a child upset by a nightmare isn’t being unreasonable.
Repeated episodes can sometimes occur alongside another problem that interrupts sleep, such as obstructive sleep apnea—a condition in which breathing repeatedly becomes partly or completely blocked during sleep. Loud, frequent snoring or gasping deserves attention rather than being assumed to be part of a night terror.
What Should You Do During a Night Terror?
Focus on safety rather than trying to wake your child. Shaking, shouting, or repeatedly questioning them may increase confusion and agitation.
Stay nearby and calm. Use a quiet voice if you speak.
Give them space. Don’t hold them down unless brief intervention is necessary to prevent immediate injury.
Prevent falls or collisions. Move nearby hazards and gently guide them away from stairs or sharp furniture if they get up.
Let the episode pass. Once your child settles, allow them to continue sleeping.
If episodes involve walking, keep pathways clear, avoid top bunks, and consider age-appropriate stair gates. Secure exterior doors and windows in a way that still allows adults to exit quickly in an emergency.
The next morning, there’s usually no need to describe the event in frightening detail. If your child asks, a simple explanation—“You had a restless moment while you were asleep, and I stayed with you”—may be enough.
How Can You Help After a Nightmare?
A child who wakes from a nightmare needs reassurance that they’re safe now. Offer a hug, listen briefly, and explain that a dream can feel real without actually happening.
Avoid dismissing the fear with “That’s silly.” You also don’t need to launch a detailed investigation of the dream in the middle of the night.
A soft night-light, a familiar comfort item, or a brief, predictable check-in may help your child return to sleep. Keep the room quiet and the interaction low-key rather than turning on a show or offering a phone.
If the same fear keeps returning, talk about it during the day. Younger children may find it easier to draw the dream or imagine a different ending than to explain their feelings at bedtime.
What Can You Do to Reduce Sleep Disruptions?
You can’t prevent every nightmare or night terror, but protecting your child’s sleep can help.
Keep bedtime and wake-up time fairly consistent, including weekends.
Allow enough time for sleep. An earlier bedtime may help when your child is overtired.
Build a quiet bedtime routine. Reading, bathing, and a few calm minutes together can make the transition easier.
Limit frightening or stimulating content, especially near bedtime.
Avoid caffeine, including caffeinated sodas and energy drinks.
Make room for daytime conversations about school worries or changes at home.
For families in Jackson and Madison County, the back-to-school transition can be a common sleep challenge. A child who stays up on a summer schedule but suddenly needs to wake early may become overtired. Moving bedtime earlier gradually before school starts can make that adjustment gentler.
Don’t start melatonin or other sleep products specifically for these episodes without discussing them with your child’s pediatrician. They aren’t a routine fix for nightmares or night terrors.
When Should You Call the Pediatrician?
An occasional episode in a child who otherwise sleeps and functions well can usually be watched at home. Contact your pediatrician if:
Episodes are frequent, increasing, prolonged, or regularly disrupting family sleep.
Your child is getting hurt or leaving the bedroom during episodes.
Daytime sleepiness, irritability, attention difficulties, or school performance changes appear.
Nightmares cause bedtime avoidance or ongoing distress.
Your child snores often, gasps, or seems to pause breathing during sleep.
Episodes begin after a medication change or follow a frightening experience.
You’re unsure whether what you’re seeing fits either pattern.
Keep a short sleep log with bedtime, episode timing, what happened, and how your child felt the next day. A brief video may help your pediatrician if you can record safely without delaying care or leaving your child unprotected.
When does a nighttime event need immediate attention?
Seek prompt medical assessment for unusual repeated stiffening or rhythmic jerking, especially if episodes look identical each time. Seizures and other conditions can sometimes resemble sleep disturbances.
Call 911 for severe trouble breathing, blue or gray lips, ongoing convulsions, or unresponsiveness outside the apparent sleep episode. Being difficult to wake during a typical night terror is different from remaining unresponsive afterward. Serious injury also requires immediate care.
Bottom Line
Nightmares usually leave a child awake and looking for comfort. Night terrors can look more dramatic, but the child is still partly asleep and typically won’t remember them.
Reassurance helps after nightmares; calm supervision and safety come first during night terrors. If episodes keep happening, affect daytime life, or don’t seem to fit either pattern, you don’t have to sort it out alone. Your pediatrician can help you decide what needs a closer look.
