Shocked While Asleep

Our house in the metro was one of those steel buildings built in the area - and actually one of the first of its kind when it was built in 2002. I am relieved to know this earlier from the person whom we bought the house. I was shocked in the middle of my sleep last night when I felt my bed shaking faintly. I though it was an earthquake, but it was only me - for some reason I was trembling enormously from my abdomen.

But this fact, after learning about it, made me at ease.
