..btw, dont worry about the RV'ing comment. It was the 1st thing that came to mind after discounting spirits, which given your properties history, it what it probably is.

Any cold/hot spots when this "thing" is around? Electrical gremlins? Pet's staring at a particular spot for no reason, or refusing to go to certain parts of the property?

Any small items [keys, watch etc] recently go missing?
