Symptoms

By Mayo Clinic staff

Nightmares are parasomnias — undesirable experiences that occur during sleep. You've had a nightmare if:

  • Your dream wakes you up
  • You feel scared, anxious, angry, sad or disgusted as a result of your dream
  • You can think clearly upon awakening, and can recall details of your dream
  • Your dream occurs near the end of your sleep time
  • Your dream keeps you from falling back to sleep easily

When to see a doctor
Occasional nightmares aren't usually a cause for concern. If your child has nightmares, you can simply mention them at a routine well-child exam.

Talk to your doctor earlier if your or your child's nightmares:

  • Become more frequent
  • Routinely disrupt sleep
  • Cause you or your child to fear going to sleep
