A common 2am scene: a child screaming inconsolably, eyes open, not responding to your voice, sometimes thrashing or running. Parents almost universally describe this as “a nightmare” — but in most cases, it isn’t.
What’s described above is a night terror (technically: confusional arousal / sleep terror). It is a fundamentally different event from a nightmare, and the response that helps one makes the other worse.
The distinguishing features
Nightmare:
- Usually occurs in the second half of the night (after 2am).
- Child fully wakes, is upset but coherent.
- Recognizes the parent and is comforted by their presence.
- Often remembers the dream the next morning.
- Returns to sleep within 10–20 minutes once comforted.
Night terror:
- Usually occurs in the first 1–3 hours of sleep.
- Child appears awake (eyes open, screaming) but is actually in deep NREM sleep.
- Does not recognize the parent. Often resists touch or worsens with contact.
- Has no memory of the event the next morning.
- Resolves on its own within 5–20 minutes; the child returns to deep sleep with no memory.
The bedside test: try to make eye contact and ask “do you see me?” If the child responds appropriately, it’s a nightmare. If they look through you, scream louder, or are uncomprehending, it’s a night terror.
What to do
For a nightmare: sit with the child. Soft voice. Validate the fear (“that was scary”). Stay until they’re calm enough to sleep. Brief discussion in the morning is fine; don’t relitigate the dream content.
For a night terror: do not try to wake the child. Do not try to soothe them in the conventional sense. Stay nearby, keep them physically safe (especially if they’re moving), turn down the lights, and wait. The episode will end on its own. The child will return to sleep with no memory.
Trying to “wake” a child from a night terror prolongs it and often produces a confused, distressed full waking that’s harder to recover from than the original event.
When to investigate further
Night terrors are most common between 3 and 8 years old and almost always benign. They become worth investigating if:
- They occur more than twice a week for over a month.
- The child is also sleepwalking, snoring, or mouth-breathing.
- The episodes are escalating in intensity.
- The child reports daytime sleepiness or behavioral changes.
Persistent night terrors are sometimes a sign of pediatric sleep apnea (especially with snoring) or, less commonly, of a need for medical evaluation. For one or two a month with no other symptoms: nothing to do but wait it out.
