I was a big fan of scary survival-horror-ish games in my early teens. My favs from the genre to this day are Haunting Ground and Rule of Rose.
Some others worth mentioning are: Fatal Frame, Silent Hill 1-4, Echo Night: Beyond, The Witch's House, Dreaming Mary, Ib (not nearly as scary as others on the list but it still counts) and probably some others I'm forgetting because I suck. Spooky's House of Jumpscares is also deceptively good (though it's on the sillier side.) I also, kind of, admittedly, like FNAF 1. It had good atmosphere if nothing else.
As for movies: Ju-On, The Ring, The Others, Cabin in the Woods, Oculus, Silence of the Lambs, and The Skeleton Key are some of my favorites (that I can remember off the top of my head)
Give me those spooks I just eat them up
