Nightmares

We’ve all been visited by a nightmare. Then, upon waking, we’ve all known that frightening moment where we cannot decipher reality from dream. For comfort, we tell ourselves nightmares are not real.
But they are.

Nightmares are described as small, swift creatures of deepest black fur that can move on all fours or squat on their hind haunches. They feed on fear, figuratively and literally. Daiyu describes them as their pets. They mostly reside in the Dreamworld but can appear in the waking world when a nightmare is inflicted upon a person.
