I can't stop thinking about what the Banned Topic might be!

As I'm almost certain to get nightmares of some kind now - thanks - please, if you could, tell me I'm not likely to figure it out by accident, while dreaming. Because, um, I'm getting a very creeped-out feeling from all this.

Edit: I tried to stop thinking about what it might be. It's not working. I've come up with several options, some of the less horrifying thanks to cousin it, but those.. not saying.
