Night Terror or Nightmare — How Do You Tell the Difference?

One is harmless, one needs a response. Plus: what you should do in the first 30 seconds.

Answer in 30 seconds

The key difference: during a night terror the child is still asleep — their eyes may be open, but they do not respond to you. With a nightmare they wake up and can often describe what frightened them.

01 Recognition

How can I be sure what is happening?

Short answer
Check the time: night terrors typically occur within the first 2–3 hours after falling asleep. Nightmares are more common after midnight, when the proportion of REM sleep increases. And: can your child speak to you? If so, they are awake — and have probably had a nightmare.

During a night terror the child often sits upright, screams, sweats, and has open eyes — but is unreachable. This can look alarming to parents, yet it is biologically harmless. Intervening prolongs the episode. Stay nearby, make sure they cannot hurt themselves, and wait.

02 Nightmare

What helps with a nightmare — and what makes it worse?

Short answer
The most important things in the first 30 seconds: establish physical closeness, use a calm voice, do not switch on bright lights. Questions like "What did you dream?" can help — but do not force it.

What amplifies nightmares: exciting screen content late in the evening, general sleep deprivation, and unprocessed daytime stress. A regular evening ritual with a calm story is the best protection.

Frequently asked questions.

Night terrors have been more frequent for weeks — is that normal?

Clusters are normal during developmental spurts, fever, or sleep deprivation. If episodes occur several times per night or persist for months, a check-up with the paediatrician is recommended.

Should I tell my child about their nightmares?

Only if they ask. A conversation the next morning can help, but do not force it. Some children prefer to leave those images behind.
