Boom
Life got busy last night, so I didn't get to bed until about 11:45pm, with the alarm set for 6:05am. I was sleeping soundly, or so it seemed, when a boom shook the house, like a plane crashed into the roof or something. The time projected on the ceiling said it was 4:05am.
A thunderstorm cell passed right over the house. There was almost no delay between the flash and the bang, and the whole bedroom got really bright, even through the heavy shades we use on the outside of the windows. Each set had about three or four closely spaced booms, and there were five or six sets. The rain didn't start falling until the third strike, and it was heavy, but not the heaviest we've seen.
After it passed I slept until the alarm went off, way too soon...
