I live in a single two story(3 with attic) older home. It is a tall and thin home. I noticed that when we get high winds my bedroom on the second floor feels like it's shaking. I had my brother take a look around and we discovered that when you bounce in the one corner of my room everything in the room shakes. Obviously something isn't right!! This phenomenon doesn't happen in the other rooms. Any ideas of what this could be?? It's a bit unnerving!!
