Thriller/Horror/Phycological movies worth watching?

Hi there! It's my first time posting in a while and I thought about posting this. What movies did you enjoy watching and were worth the watch? I enjoy watching movies that usually involve thriller/horror/psychological/mind-bending/mind game/mystery/ominous/suspense. I mostly like dark movies that make me use my head. Thriller is something I thrive for in movies these days. What do you think about these types of movies and are there any you would recommend?
