I hear ya!! I was just getting ready to power nap. There went that idea.
BTW, for the archives of "Do animals sense quakes?" please note that my muttly dog slept through the entire jolt lying on his back on his futon with his legs up in the air, snoring softly.

Okay, now this is weird. About 20 minutes ago, both of my cats, who were sleeping on different chairs, both woke up suddenly, and started tearing around the house.
The weirdest part is, I live in So-Cal, not anywhere near SF! I find it hard to believe they could have sensed something that far away, yet they appear to have reacted at the same time as your quake.
Maybe I should be on the alert still.
