Many sleep disorders tend to present themselves predominantly in childhood, before the patiend grows out of them later in life.

The word 'incubus' (from the Latin in: upon, & cubare: to press) reflects the medieval belief that sleep terrors are caused by a devil pressing on the chest of the sleeper, although this cause is scientifically yet to be proven -) On the other hand, the phrase 'incubus attacks' is commonly used to refer to sleep terrors in adults. In addition, 'pavor nocturnus' is used most commonly to refer to sleep terrors in children.
