When I walk down the hallway to the bathroom at work, some of the tiles in the false ceiling pop up and sometimes vibrate noisily as I walk past. I assume it has something to do with a vacuum created by the air conditioning system, and a pressure differential caused by my approach. But I can't help imagining it's an upside-down version of those creepy little things (apparently called Snatter Goblins) that rotate the paving stones when Sarah draws lipstick arrows on them in Labyrinth. And I don't like it.
