There's more than one kind of "being scared". Some people like that campfire story exhilaration you get. It's playful and makes you possibly feel on edge or sharp.

Some people just like the myriad of emotions that different stories and evoke and how some story tellers and performances go about evoking them.

What I like about horror most is what I like about any genre of story. Seeing something captured that would be so difficult for me to describe. Or something I'm aware of but I'm not even aware of it. Or something I'm aware of but it's a forgotten notion. Or many many things I'm familiar with faint or vibrant that are portrayed as an amalgamation by a creator, or by chance, that obviously had a lot of influences with things I know or fit my taste.

Or, most relevant, seeing something just really well done. Understanding exactly what they were going for and being able to say "Damn. They did it." Just witnessing art and what it offers or getting to be entertained.

I like to pretend that the Cube movies after the first don't exist and Kazan got to enjoy whatever life he has.

Agreed and I'd like to add; nothing should be considered a sign of virtues other than things that directly display a virtue. The amount that people have appreciated or given me credit for the most basic kindnesses that take no effort and nothing from me is truly incredible. Not just desperate people or people in need either. And there's nothing wrong with appreciating stuff like that, but compared to my actual morals the stuff I'm referring to is more like manners. It's just a formality. Do it for anyone.

Man, the sporadic amount I've played a bit of vanilla then modded minecraft the recipe list is extensive enough for me.

Creep (2014) is like.. the entire point of the movie is this vibe.

While his other work is actually a bit less horror coded if you liked Perfect Blue that much you should check out the rest of Satoshi Kon's other works. Particularly "Paprika" and "Paranoia Agent". While they aren't about dread and confusion like Perfect Blue I still think you'll like them because otherwise they're very thematically connected with a lot of exploration of identity/ego vs reality and the dissonance it can cause.

Also I'd recommend Oldboy (2003) and I Saw the Devil. Not the same unsettling vibe as your request, either, but they do mess you up.
