Recommend some of your favorite psychological horror movies! - eviltoast

I watched Possession(1981) for the first time last night and holy heck was that a mindf*ck of a trip. I had heard great things about it and how it had a cult following but I went in blind otherwise. Loved almost everything about it, very surreal and the film itself contorts to things I can’t even describe by the end - solid 8/10

I also viewed Jacob’s Ladder(1990) last week and that was a wild ride as well!

Anyone have any personal favs or recommendations? I’m not a horror fan by default but just trying to watch some gems I’ve missed during the spooky season 🎃
