>For me, I've always called it the "school at night" phenomenon.

It's funny, I've always loved that kind of environment. Quiet high school hallways after everyone's left, empty university buildings late at night, offices after hours, even empty offices that haven't been moved into yet. For me it evokes feelings associated more with watching a rainy day from inside, or lofi-girl with headphones studying.

I understand why it can evoke horror or unsettling feelings for people, but for me the first word that comes to mind is just "peaceful".

Even the environments in the Backrooms trailer - minus the obvious horror elements - look like they would be a lot of fun to explore!
