I have had another thing happen the last couple of days. I will think I see a cat or rat or some sort of animal move along the wall out of the corner of my eye. When I look straight on, it is a bag or t shirt or something on the floor. I didn't question it when it happened at my house, because I have pets, but when it happened at my parents' house, I wondered because they have no pets at all.

Hopefully I am just misinterpreting things, but it is so strange.
