Psychological movies
Psychological horror keeps the question open. Something is wrong, and the film declines to say whether it is wrong with the world or with the person the film is following. The dread comes from not being able to trust the frame.
Repulsion is the early one that commits completely, staying so far inside its protagonist that the audience stops being able to tell which parts of the flat are happening. Rosemary's Baby is the more useful model, because its trap is social rather than perceptual: Rosemary is right that something is being done to her, wrong about what, and surrounded by people who all have reasons to call her unwell. The mechanism is older than the film and takes its name from a different one, Gaslight, in 1944.
The Shining holds the hotel and the father in frame together for most of its length, and only concedes that the hotel is real when a door somebody could not have opened is unlocked from outside. Later films name the pressure they run on: Get Out does it through race and Black Swan through a career, though Jordan Peele has been clear that Rosemary's Baby is his model, which makes that less a development than a return.
