I was lying in bed, daydreaming (because I'm not tired), plotting, and then I hear a "boom" and my bed and nightstand shake a bit. The boom felt like something hit the bed (from the corner where I was facing), but not that close, so probably outside. I checked around the house - nothing unusual. Didn't go outside to see if anything hit our house or by our house - I doubt it. The more time passes, the more it feels like I imagined it, but I'm positive I was fully awake and there was no change in my conscious state between the sound and shaking and lying in bed trying to coax myself to take a look around.
