The Nightmare Affair (Arkwell Academy, 1)

The Nightmare Affair is the first in the gripping Arkwell Academy trilogy by Mindee Arnett.
Sixteen-year-old Dusty Everhart breaks into houses late at night, but not because she's a criminal. No, she's a Nightmare.

Literally.

Being the only Nightmare at Arkwell Academy, a boarding school for magickind, and living in the shadow of her mother's infamy, is hard enough. But when Dusty sneaks into Eli Booker's house, things get a whole lot more complicated. He's hot, which means sitting on his chest and invading his dreams couldn't get much more embarrassing. But it does. Eli is dreaming of a murder.

Then Eli's dream comes true.

Now Dusty has to follow the cluesۥboth within Eli's dreams and out of themۥto stop the killer before more people turn up dead. And before the killer learns what she's up to and marks her as the next target.
