Okay, what it was was that in the lobby there are elevators that I never think about because they don't come to my floor, but as I was passing one a maintenance man walked up to it, pushed his hand flat against it, and it swung right in. A secret room! There seemed to be all sorts of dangerous looking mystery machinery in there and then he'd gone in and the door fell shut, and there was no one around for me to show my stunned face to. It was like something I'd dream.

In related news, I'm feeling like I'm in one of those dreams where everyone disappears and I'm the only one left.
