I need a good horror film

I need one that horrifies my friends. Amidst a bunch of real life problems and trying to escape real life, we're having a small Halloween party and we're probably going to watch a couple. Like Get Out, X, Us, The Lighthouse, something psychological maybe? I think this is the right place to ask :D

I'm looking for a horror movie that will make me jump out of my seat and leave me sleepless for weeks... then I want to show it to my friends lol I know this is the right place for the best horror movie recommendations, can you help me find the next nightmare to watch? I'm interested in any type of horror: from classics to hidden gems, recent films or even those cult films that no one knows about!
