I never got really super into this subculture thing, or whatever it is, but I vaguely recall skimming things like a subreddit devoted to it, ages ago. I want to say when it was “starting” but then nothing ever really starts or ends. Definitely Pre-Covid though. Anyway, IIRC the focus was not on the horror, maybe a slight unease, but mostly the uncanniness.

I think this is just how things evolve. Creepy is a very strong sentiment that is somewhat aligned with uncanny, so it isn’t that surprising to see uncanny collapse into it over time.

But having spent a lot of time in empty classrooms, auditoriums, and hallways, waiting for students to show up, it’s more of a nostalgic feeling to me.
