So I love a lot of horror, my three favorites are generally Body horror, Psychological horror, And Paranoia based horror. There a fair bit of overlap here, and as long as it's a thematically resonant story I'll put any horror you say on my list, but these three in particular are my absolute faves when I'm in the mood to be viscerally uncomfortable. For frame of reference my favorite horror movie is the thing 1982
