Ok, I just heard something knocking on the floor. I think it was my son's shoe on the floor, but with him being a three year old, I can't get a straight answer if it was him or not. It could have been someone knocking from below. My dog had no reaction to it, so it is either something normal about the house, or was my son, or a hallucination. I think I am going downstairs with a big knife, just to check things out. (and the telephone)

I know it is ridiculous to be thinking this way and I am trying to crowd it out with positive thoughts. It has taken a strong hold in the back of my mind.
