Nothing out of the ordinary
It's late and I've just gotten home from work, I walk up to the front door and stick my key in. When the familiar, soft click reaches my ears I push it open. Behind it the dark hallway greets me. Normally I don't hesitate to enter, but today something feels... off. I remain standing just outside, staring inside the building. It looks the way it has always looked. It smell the way it has always smelled. So what is it that makes me feel this way?
