"Welcome to your fears of the monsterkind humans! Tonight you will see what humans before the war were afraid ͏of!"


Nightmare Story takes place in an AU where monsters never existed, but children and adults still fear that monsters might hurt them.

In this AU, the monsters are dreams who live in the dream void until someone has a dream. At night they are called Nightmare Monsters. They are able to go into any dream, although most go for children and teenagers. They feed off of pain and death.
