Somniphobia is defined as "a persistent, abnormal, and unwarranted fear of sleep", and this condition causes thousands of people major distress every year. There are many reasons why people may suffer from somniphobia, as with any fear: they may have had repeated bad experiences with nightmares/night terrors as a child. Known by many names—somniphobia and fear of sleep being the most common—the problem often significantly impacts quality of life. It can cause panic attacks, and symptoms include shortness of breath, nausea, sweating, irregular heartbeat and a sense of impending doom/dread.

Also known as hypnophobia, this is the abnormal fear of falling asleep. Oftentimes it can be the result of people feeling as though they are losing control and nightmares have been known to cause it as well.
