I'm thinking that some unauthorized person is sharing your living space with you without your knowing it.
Don't laugh. I heard about it on T.V., and it's more prevalent than you may think.
You may want to set up a webcam to monitor the goings-on while you are not home.
You may also want to post your query on the unsolvedmysteries.com website. Again, don't laugh. Someone in the reading audience just may have the answer which you seek.
