Is night terror a mental disorder?

Night terrors, also known as sleep terrors, are not classified as a mental disorder but rather as a sleep disorder. They typically occur during non-REM sleep and involve episodes of extreme fear, confusion, and physical symptoms like screaming or thrashing, usually without the person recalling the event upon waking. While they can be distressing, especially for those witnessing them, they are more common in children and often outgrown. If night terrors persist or significantly impact daily life, consulting a healthcare professional may be advisable.
