That reminds me of what happenned to my house key. I went out one night and didn't want to take a purse so I stuck my ID, credit card and housekey(that I knew I should have never taken off my keyring) in my jeans pocket. I know I had the key when I got home because I obviously used it to open the door, but the next morning when I looked on my dresser where my ID and credit card was from emptying my pockets...no key. I looked everywhere...I knew it was in the house...I just couldn't understand how everything else was on the dresser but not the key. I finally gave up and had a couple extra keys made. Well...3 months later as I was getting into bed, I felt something cold fall across my leg. I jumped up panicked because I thought it was a bug... Low and behold it was my lost house key laying in my bed. I have no idea how it got there. It couldn't have been in the bed all that time because all the sheets and blankets had been washed numerous times since I lost it. To this day, it's a mystery to me...of course, I just blamed it on the ghost.
