Dream Catcher Series by Lisa McMann

For seventeen-year-old Janie, getting sucked into other people's dreams is getting old. Especially the falling dreams, the naked-but-nobody-notices dreams, and the sex-crazed dreams. Janie's seen enough fantasy booty to last her a lifetime.
She can't tell anybody about what she does they'd never believe her, or worse, they'd think she's a freak. So Janie lives on the fringe, cursed with an ability she doesn't want and can’t control.
Then she falls into a gruesome nightmare, one that chills her to the bone. For the first time, Janie is more than a witness to someone else's twisted psyche. She is a participant.

For Janie and Cabel, real life is getting tougher than the dreams. They're just trying to carve out a little (secret) time together, but no such luck.

Disturbing things are happening at Fieldridge High, yet nobody's talking. When Janie taps into a classmate's violent nightmares, the case finally breaks open -- but nothing goes as planned. Not even close. Janie's in way over her head, and Cabe's shocking behavior has grave consequences for them both.

Worse yet, Janie learns the truth about herself and her ability -- and it's bleak. Seriously, brutally bleak. Not only is her fate as a dream catcher sealed, but what's to come is way darker than she'd feared.... 

Janie thought she knew what her future held. And she thought she’d made her peace with it. But she can’t handle dragging Cabel down with her.
She knows he will stay with her, despite what she sees in his dreams. He’s amazing. And she’s a train wreck. Janie sees only one way to give him the life he deserves: She has to disappear. And it’s going to kill them both.
Then a stranger enters her life — and everything unravels. The future Janie once faced now has an ominous twist, and her choices are more dire than she’d ever thought possible. She alone must decide between the lesser of two evils. And time is running out. . . .
