I am looking to traumatise my girlfriend.

i love horror movies, my girlfriend doesnt. We watched hereditary, blair witch, the babadook, and the one that scared her the most was Smile… (we watched full volume and the jumpscares were fairly effective 😭). Gore doesnt exactly scare her, its just gross to her. I suppose thats the point but hey, i want a movie so scary she will want me to turn it off, but not a movie so underground that its black and white made in 1912 and in japanese. I thought this would be the best place to ask so what you guys got?
