Two hours after going to sleep, I awoke to a shrill alarm with a start, kicking off the bed and into the air. Three things went through my head in the second or so before I touched down.

1. Hmmm, that's not my alarm. It's much too high-pitched, and isn't intermittent.
2. Gosh, there's a lot of smoke in here.
3. Hey, is that the ground?
