Help me out, please??

Yo guys, I'm making a oneshot manga for Yen Press's New Talent contest. I'm having a crapload of trouble developing the story into something at least somewhat different than everything that's out in the world now. I really need people's opinions on the stuff I've developed so far! So here we go:

Ayumu is a 17 year old high school student ostracised from her family and peers for one reason: She cannot differentiate between the world of her dreams and reality. Most days are fairly normal, with the occasional classmate appearing as a plant or harmless animal to her eyes. But the days when the dream eclipses her senses are the worst. The students that harass and bully her are Ayumu's demons. They are the murderers and vicious beasts of the dream, and she is constantly tormented by their likeness whether awake or asleep. Her friend Miharu is the one person who can bring Ayumu out of her dream-induced fits of anxiety. But will his presence be enough to keep Ayumu from slipping into complete madness?

Yeah, I fail at making this sound like a not-cliched manga...

Really need feedback, help a girl out, pretty please????
