Tremours

Last night I dreamed that there was a tremour. It woke me up, and I lay there in the dark wondering if it was real or imagined. The night before there actually was a real tremour, about 4 point something although I didn't feel that one. Every building I go into, I seem to spend a lot of time looking at the walls for cracks or other signs of weakness, and wondering about which is the best way out of there, or which corner to duck under. Hopefully I'm just being ridiculous and paranoid.
