I've never been one to believe in the paranormal, but sometimes you have to wonder. I've been looking for a logical explanation for moved or missing items around here too. One missing item struck me as particularly odd. My sister, a devout Catholic, gave me a bottle of holy water a while back. I try to be accepting of other people's beliefs, so I accepted it without issue and put it on a shelf in my closet, and didn't give it much thought. Recently I noticed it was gone without a trace. This worried me, because I live alone and no one is ever in the house without me present. The closet is also in Rocco's room, which I keep people out of because he isn't comfortable with most people. I searched the house high and low to see if I could find it and determine if anything else was missing. Nothing else was missing, but I found a few other items in odd places.
I really doubt that someone broke in, leaving no signs of forced entry, only to steal a bottle of holy water out of my closet and leaving my computers, jewellery, and other valuables intact. Maybe I'm a sleepwalker and just don't know it.
