its a freaky thing when you smell something that doesn't exist.. the worst part is ..last year.. when the north east was hit by the earth quake.. my kids were down stairs and I was upstairs..all of a sudden i saw the house shaking and my gliding chair was rocking the wrong way.. I called them up and they didn't feel a thing.. (i thought that was the biggest hallucination i had yet) until i sw neighbors and put on the news.. one.. that was scary
