A sleep disorder is just what its name implies: something abnormal about the way a person is sleeping. It might be that he or she cannot get enough sleepy as is the case in insomnia (in-SOM-nee-a). In hypersomnia (HY-per-SOM-nee-a), the individual sleeps too much. In still other kinds of sleep disorders, events such as night terrors may interfere with sleep.
