I know this is something some of you experience on a regular basis, but it was my first time. They happen here but not frequently. It happened about 1:15 am sunday morning, 5.2 on the ricter scale. My dog had driven me nuts all evening, he was restless and whining etc. My husband was on his way home from a tagball outing with the guys. I was asleep and I woke up because the bed started shaking and the dog jumped up and ran out of the room, I got up and my heart was racing, I was still half asleep so I was standing there trying to figure out if I was shaking or if the house was shaking. It was surreal! I thought I had lost my mind, so I went back to bed. I didn't find out what it was until I got up later that morning. I told my husband it was a good thing I thought I had lost my mind, because if I had of realised what was going on I probably would have panicked!
