Sleep terrors, which are also called night terrors, are when you have a period of screaming, crying, or intense fear while you are still sleeping. You may also sometimes wave your arms and legs or sleepwalk. This usually lasts for up to a few minutes.
Most people do not remember their sleep terrors.
They are most common in young children, who usually outgrow sleep terrors by the time they are teenagers.
Sleep terrors are a type of condition called parasomnia. They are not the same as nightmares.
Occasional sleep terrors aren't a cause for concern, but if they happen often, led to safety concerns, or regularly disrupt sleep, you can reach out to a doctor.
