It’s a bit hard to describe but I felt like both had moments of spiraling confusion with the protagonist watching their worlds fall apart around them that I found really captivating.
I’m trying to think of other examples but The Fall and The Father are ones that came to mind. They are both fantastic films I’d highly recommend.
frefi@lemmy.dbzer0.com mentioned mother! (2017) which was the other example that was on the tip of my tongue.
