SOMETHING SO STRANGE

The other day my wife came home and took off her shoes placed them by the front door,the next morning they was gone,we looked and looked,when i got my kids up we looked again but no luck.That night the same thing,shoes by the door,next morning they was gone.Well today i was reading a letter from a preacher i got,the lights went off then back on,i saw something out of the corner of my eye,like a rat.i walk to the bedroom door and by the end of the couch by the bedroom door the first pair of shoes,they was not there before,4 people turned this house upside down 2 days in a row,what in the hell caused this?
