The Nightmare, to my knowledge, is not inspired by mythology.

Like the Gazer *cough*beholder*cough*, the nightmare could trace it's origins back to Dungeons and Dragons where it became a common trope in fantasy settings.

Because demon horses are too badassed and "Nightmare" is too cool and punny to not be used.
