Night Terrors vs Nightmares: The 6 Differences

It’s the middle of the night. Your child is crying, shouting, or sitting up in bed with a terrified look on their face. You rush in, heart racing, and try to comfort them.
But something feels strange.
They don’t seem fully awake. They may not recognize you. They may push you away. Or maybe they wake up clearly upset and tell you exactly what scared them.
That difference matters.
Night terrors vs nightmares can look similar from the doorway, but they happen in different parts of sleep and need different responses from you.
Quick answer: night terrors vs nightmares
| Difference | Night terror | Nightmare |
|---|---|---|
| When it happens | Usually early in the night | Usually later in the night |
| Sleep stage | Deep non-REM sleep | REM/dream sleep |
| Is your child awake? | Not really | Yes, usually awake |
| Do they remember it? | Usually no | Often yes |
| Can you comfort them? | Often difficult | Usually yes |
| Best response | Keep safe, stay calm, wait it out | Comfort, reassure, help them resettle |
1. Night terrors usually happen earlier in the night
Night terrors often happen during the deepest stages of sleep, usually in the first part of the night. That is why they may happen before you have even gone to bed.
Nightmares are different. They usually happen later, when dreaming is more active.
A simple clue:
If your child wakes upset around 10 PM, confused and unreachable, it may be a night terror.
If your child wakes around 3 AM, scared and able to describe a dream, it may be a nightmare.
2. During a night terror, your child is not fully awake
This is the part that can feel most frightening.
During a night terror, your child may cry, scream, sweat, breathe fast, stare, kick, or thrash. But even if their eyes are open, they are usually still asleep.
That is why they may not respond when you say their name. They may not seem to know you are there. They may even push you away if you try to hold them.
With a nightmare, your child usually wakes up. They may be frightened, but they can often recognize you and accept comfort.
3. Nightmares are remembered. Night terrors usually are not.
After a nightmare, a child may say:
“I dreamed there was a monster.”
“I couldn’t find you.”
“Someone was chasing me.”
After a night terror, they often remember nothing in the morning.
That can feel unsettling as a parent. You watched something intense happen, but your child may wake up cheerful and confused by your concern.
This is one reason night terrors are often harder on parents than on children.
4. Night terrors look more physical
Nightmares can involve crying, fear, and needing comfort.
Night terrors often look more like the body has gone into alarm mode. You may see:
- sweating
- fast breathing
- screaming
- sitting upright
- kicking or thrashing
- a glassy-eyed stare
- confusion
- difficulty waking
The key is not just intensity. The key is whether your child seems reachable.
If they are terrified but comforted by you, it is more likely a nightmare. If they are terrified but cannot really connect with you, it may be a night terror.
5. The best response is different
For a nightmare, comfort helps.
You can say:
“You’re safe. I’m here.”
“That was a scary dream. It’s over now.”
“Let’s take one slow breath together.”
You can offer a nightlight, a cuddle, or a small calming ritual before helping them return to sleep.
For a night terror, the goal is different: safety first, calm presence second.
Try not to shake them awake. Trying hard to wake a child during a night terror can make them more confused or agitated.
Instead:
- stay nearby
- speak softly
- move dangerous objects away
- gently guide them back if they try to climb or walk
- wait for the episode to pass
Most night terrors end on their own, and many children fall back into quiet sleep afterward.
6. Night terrors are not usually a sign something is wrong
Night terrors can be deeply scary to witness, but occasional night terrors are common in children and often fade with age.
They may be more likely when a child is overtired, stressed, feverish, sleeping irregularly, or having disrupted sleep.
That does not mean you caused them. It means your child’s sleep system may be overloaded.
A steadier bedtime rhythm can help:
- earlier bedtime during tired phases
- predictable wind-down routine
- calm room environment
- less rough play before bed
- fewer sleep interruptions
- tracking patterns if episodes repeat
If episodes happen around the same time each night, some clinicians may suggest scheduled awakenings, where a parent gently wakes the child shortly before the usual episode time. Ask your pediatrician before using this as a plan.
When to talk to a doctor
Mention night terrors at your child’s next checkup if they happen occasionally.
Talk to a pediatrician sooner if:
- episodes become frequent
- your child could get injured
- they leave the bed or room
- sleep is badly disrupted
- your child is very sleepy during the day
- episodes continue into the teen years
- something about the episode feels unusual to you
You do not need to panic. But you also do not need to handle repeated scary nights alone.
What to say the next morning
If it was a nightmare, your child may want to talk about it.
If it was a night terror, they may not remember anything. In that case, you do not need to make it dramatic.
You can simply say:
“You had a hard sleep moment last night. You’re safe. Your body settled again.”
Then move on gently.
For anxious children, too much morning detail can sometimes create a new fear of sleep. Keep the tone calm and ordinary.
A Soothly-style bedtime reset
After a nightmare, a short personalized story can help a child feel safe again.
Not a lecture. Not a long explanation. Just a gentle story where their fear becomes something they can face.
For example:
“Tonight, the Worry Shadow came tapping at the window. But Sami remembered the little lantern in his chest. It did not make the dark disappear. It helped him see that he was not alone in it.”
That is the kind of moment a child can carry back into sleep.
Create a calming bedtime story for the fear your child is carrying tonight
