Fear of going to bed

An abnormal and persistent fear of going to bed. Sufferers of this fear experience anxiety even though they realize that going to bed normally should not threaten their well-being. However, because they worry about having nightmares or wetting the bed, they often remain awake and develop insomnia. Insomnia then can become a real threat to their well-being. Fear of going to bed is termed "clinophobia," a word derived from the Greek "klinein" (to bend, slope or incline, as one does during sleep) and "phobos" (fear). Another medical term containing "clino-"is "clinodactyly" meaning a finger that is curved to the side.
