Night terrors and nightmares

Also called Sleep terrors

Night terrors are when someone screams, shouts or thrashes around in their sleep, often with their eyes open, but is not fully awake. They are most common in children aged 3 to 7 and usually happen early in the night. The child does not remember them. Nightmares are frightening dreams that wake you up, and can affect people of any age.

What it is

Children usually grow out of night terrors. It is best not to wake the child, but stay with them and keep them safe.

Regular bedtimes, enough sleep and reducing stress can help. Frequent nightmares in adults can be linked to stress, trauma or medicines.

Common signs

  • Screaming, shouting or thrashing during sleep
  • Seeming awake but not responding
  • Not remembering the episode
  • Waking up frightened from a vivid dream (nightmare)

How it is usually diagnosed

  • Questions about the episodes
  • A sleep study, rarely

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • A sleep diary with the times of episodes
  • Videos of episodes, which can help doctors

Questions to ask your doctor

  • Could these be seizures rather than night terrors?
  • How can we keep our child safe?
  • Could stress or trauma be playing a part?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Jerking movements, breathing pauses, or episodes with injury: get medical advice promptly
