Nightmares And Night Terrors
What causes nightmares and night terrors in a 5-year-old?
Nightmares and night terrors at age 5 are common and usually harmless. Nightmares are frightening dreams in REM sleep that a child remembers; night terrors are partial wakings from deep sleep that they don't recall. Both are driven mainly by over-tiredness, irregular routines, stress and illness, and tend to settle as sleep matures.
A child who wakes screaming at midnight, or sobs from a bad dream, sends every parent's heart racing — but at five, both are usually a normal part of a developing brain.
In short
Nightmares and night terrors in a 5-year-old are common, mostly harmless, and rooted in how a young brain cycles through sleep. Nightmares are frightening dreams that wake your child from later, dream-rich (REM) sleep — they remember them and want comfort. Night terrors happen in deep, dreamless sleep earlier in the night — your child seems terrified, may scream or thrash, yet stays asleep and remembers nothing in the morning. The biggest drivers are over-tiredness, irregular sleep routines, stress or big changes, and sometimes illness or fever.Why they happen
A five-year-old's sleep architecture is still maturing, and the brain shifts between deep and dream sleep many times a night. Night terrors arise when the deep-sleep system doesn't transition smoothly — a partial waking where the body is alarmed but the mind is still asleep. They are more likely when a child is over-tired, sleep-deprived, unwell or feverish, or off their usual schedule, and they often run in families.Nightmares come from REM sleep and are more tied to daytime experiences — a scary story or screen, a stressful day, starting school, a new sibling, or worries the child can't yet put into words. Both tend to settle on their own as sleep matures, and neither means something is wrong with your child.
When to seek advice
Most settle with steady routines and reassurance. Do speak with a clinician if episodes are very frequent, cause daytime sleepiness or behaviour changes, involve choking, gasping or pauses in breathing, include unusual stiffening or jerking, or persist with no settled pattern — these deserve a proper look to rule out other causes.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online form. If disrupted sleep is affecting your child's mood, learning or daily rhythm, a gentle developmental check can show where support helps. Our behavioural and emotional support teams work alongside families on routines and regulation. Start anytime at [Pinnacle](/).Trusted sources

What to watch
Frequent episodes, daytime sleepiness or behaviour changes, gasping, choking or breathing pauses, or unusual stiffening or jerking during the night.
Try this at home
Protect a calm, consistent bedtime and enough total sleep — over-tiredness is the single biggest trigger for night terrors. Wind down with quiet, screen-free time and a predictable routine.

Frequently asked
What is the difference between a nightmare and a night terror?
A nightmare is a frightening dream from later, dream-rich sleep — your child wakes, remembers it and wants comfort. A night terror happens in deep, dreamless sleep earlier in the night; your child may scream or thrash while still asleep and remembers nothing the next morning.
Should I wake my child during a night terror?
No. During a night terror it is best not to wake or restrain your child. Keep them safe, dim the room, speak softly, and wait for the episode to pass — they usually settle within minutes and return to calm sleep.
Will my 5-year-old grow out of these?
Most children do, as their sleep matures. Steady routines and enough rest help. If episodes are very frequent, involve breathing pauses or unusual movements, or affect daytime mood and learning, speak with a clinician.
