You’re tired. You’re nervous. You’re imagining things. That’s what almost everyone in the 2023 lineup gets told, right up until the walls start bleeding. Paula hears footsteps in the sealed attic, and her husband tells her she’s confused. Rosemary knows something is wrong with her pregnancy, and her doctor says it’s nerves. Chris MacNeil watches her daughter change in ways no test can explain. Mary walks out of a river alone and can’t tell what’s real anymore. Then there are slashers, which are refreshingly clear about what’s in your head: a knife, usually. Nine movies, one recurring note to self. Trust your gut. It’s not all in your head.
