Nightmares and Night Terrors in Children

This page reflects our understanding of mental health topics as of 2026. If you are reading this at a later date, some details may no longer be current, so please verify anything important against up to date sources. If you notice anything that needs updating, we would welcome you letting us know.

Nightmares and night terrors are both common in childhood, but they are different. Nightmares are frightening dreams that usually happen in the second half of the night. Children wake up, remember the dream, and seek comfort. Night terrors usually happen in the first few hours of sleep. Children may scream, thrash, or look terrified with their eyes open, but they are not fully awake, are hard to comfort, and usually remember nothing the next morning. Nightmares are often linked to stress, frightening content, or upsetting experiences. Night terrors are linked to deep sleep and are more likely when a child is overtired. Most children outgrow both.

How to Tell Them Apart

Why They Happen

Nightmares

Nightmares often follow stress, change, frightening stories or shows, illness, or anxiety. Repeated nightmares about a specific event can follow a frightening experience, such as an accident, and may be part of a trauma response, as described on the page about why people have nightmares about the same event.

Night Terrors

Night terrors happen during a partial waking from deep sleep. They tend to run in families and are more likely when a child is overtired, ill, has a fever, or has an irregular schedule. They are related to sleepwalking.

When to Seek Help

Talk to your family doctor or paediatrician if episodes are frequent, involve injury or dangerous behaviour, happen at unusual times, or seem like seizures, or if your child snores loudly or has breathing pauses. Consider psychological support if nightmares are frequent, distressing, follow a frightening event, or come with daytime fears, avoidance, or changes in behaviour, as described on the page about anxiety in children and teens. The page about sleep problems in children covers other sleep concerns.

What It Is Not

Nightmares and night terrors are not a sign of bad parenting, and night terrors are not usually linked to emotional problems. Frequent nightmares after a frightening event are worth taking seriously, but occasional bad dreams are a normal part of childhood.

Common Questions About Nightmares and Night Terrors

How can I tell if my child is having a nightmare or a night terror?

A child who wakes, remembers a scary dream, and wants comfort has had a nightmare. A child who screams but stays asleep, is hard to comfort, and remembers nothing has had a night terror.

What age do night terrors happen?

Night terrors are most common between about ages three and eight, and most children outgrow them.

Should I wake my child during a night terror?

Usually no. Waking a child during a night terror can increase agitation. Keep them safe and wait for it to pass.

Why are night terrors more likely when a child is overtired?

Night terrors happen during partial waking from deep sleep, and overtiredness increases deep sleep, so night terrors are more likely when a child is overtired.

Why do nightmares peak between ages three and six?

Nightmares peak between ages three and six because imagination is growing quickly while children are still learning to separate fantasy from reality.

How do I comfort my child after a nightmare?

Comfort your child calmly after a nightmare, reassure them they are safe, listen if they want to talk, and use a nightlight or comfort item.

Can trauma cause nightmares in children?

Yes. Repeated nightmares can follow a frightening experience and may be part of a trauma response in children.

Are night terrors dangerous?

Night terrors are not harmful in themselves, but children may move suddenly, so keep the sleep space safe.

Which night terror symptoms need a doctor's attention?

See a doctor if night terrors are frequent, cause injury, seem like seizures, or come with loud snoring or breathing pauses.

Can therapy help with childhood nightmares?

Yes. Therapy, including imagery rehearsal, can help children with frequent or distressing nightmares, especially after a frightening event.
