i'm really terrible with horror so i don't watch/read it much, but if you've never seen/read umineko no naku koro ni i really recommend it! you can watch the visual novel on youtube (or play it yourself! there's actually supposed to be an official translation coming out soon). it's a murder mystery with time loops and has a really interesting theme of like... magic vs reality and it gets pretty meta. there's also a manga that's pretty faithful, i just prefer the vn bc of the voice acting.
