Things move in my house. Not in the one of the cats must have knocked it off sort of way. I mean appear and disappear. Something may be there one day and not there the next. It's not often, and nothing really large like a couch, but I know what have experienced over the years of living here. Small things - rings, keys, bottles, pouches.
There are times I have quite literally asked the house to give something back to me, and it will show up someplace completely strange. I don't know where the stuff goes or why, but it's occasionally quite creepy.
