Alright here is what I know about this character:

- they are a species of dragon from the astral plane that come to earth disguised as stuffed animals
-they can't talk, but they are completely fully sentient.
- they eat nightmares, which infest human dreams, so most find their way into the "ownership" of a human and protect that human's family in secret
- this one has been with the same human since they were a baby, they grew up together and Dreameater considers this human to be their friend
- their human, now an adult, is plagued by particularly strong nightmares that can grow so large that they can become monsters
-Dreameater wants to protect their person from harm so they revealed their existence to the human, who is just kinda like "oh shit i have a dragon now"
-they fight monsters together in the dream world I dunno maybe they tackle the dreams of the other college kids living in the dorm with them.
-Dreameater has two stomachs - one for eating nightmares, and another that is more like a kangaroo pouch on their front that their human can sleep in. That tummy is soft and fluffy, and can be easily escaped via zipper.
-their human sleeps much better in Dreameater's tummy, and has less nightmares with them around, so they do it a lot.

that's it i should probably come up with more but honestly i'm shocked i came up with what i did
