While the Backrooms movie trailer does make it look interesting, "Backrooms" / liminal horror / Skinamarink all have the same effect on me: nothing. I figure the split of people who find it scary vs those that don't is people who can "unscare" themselves.

Like when I go into my basement at night, I can give myself the scare of "what if someone's watching ..." then go "nah" and I'm fine.

I think it’s degrees, can you open a door halfway and stick your hand into a dark room without feeling creeped out? What if instead that liminal space is the temple in Indiana Jones and you’ve seen big spiders crawling around? It’s a fear of the unknown and we’re all tuned a little differently, I think we can all evoke this feeling it just takes more or less depending on the person and how much knowledge you have about the environment.

I worked at a Target in an old mall and there was a corporate office in the basement that had been abandoned years before due to black mold. I was responsible for doing a once a week check, just making sure nobody had been down there, that place majorly creeped me out even though I had the key and had a high degree of confidence nobody else was going to be down there. Also “black mold” evokes an image of a creeping horror even though rationally I know just going down there once a week isn’t going to give me some horrible respiratory illness.

I'm not sure if it's even meant to be scary. I think of the Backrooms as closer to the world of Piranesi, or the project that took a bunch of virtual-tours of apartments for rent, and aggregrated them all into a single mega-building.

But can you “un-un-scare” yourself to enjoy liminal space horror?

that's definitely how they get you.
