horror movie recs??

so, i'm REALLY getting into horror right now (i've been into horror for a long time, but now it's classic horror movies yk).

does anyone have any good classic must watch horror movie recs? i prefer slashers, vampire stuff and religious horror stuff, but open for everything and all (especially if it has a good soundtrack.)

also it can def be older than 70s, i would love to get into black and white and silent films(already planning on watching das Cabinet des Dr. Kaligari and Dracula, they're classic classics)
