Nightmares and night terrors are usually associated with children, but sometimes they can affect adults.

When to see your GP
Nightmares do not usually cause any physical harm. But they can be disturbing or upsetting and stop you from getting a good night's sleep.
See your GP if you have regular nightmares that affect your sleep and day-to-day life.
If a traumatic event causes your nightmares or night terrors, your GP may recommend psychological treatment. For example, counselling.
