Room (2021)

Damien awakes from a terrible nightmare. Alone in his dingy excuse of a bedroom, he gets up to clear his mind. But when he opens his door, he's shocked to find that his room has repeated itself, seemingly infinitely. Before he's even able to process what the hell is happening, he hears a THUMP. from the room behind him. And slowly, the dreadful realisation dawns: he's trapped in a loop, and something else is in there with him. What follows next is a surreal, nightmarish experience that concludes with an unexpected twist.
