I've annoyed something I shouldn't have and it's followed me home. The only sensible response to this is to set up video and trigger cameras in the room it's claimed as its own, and sleep in there to goad it into doing something. If only it had picked a more comfortable room.
I've seen it, it's pure white and unfriendly and has some impressive ability with suggestion and illusion but can't cause physical harm. At least, it hasn't so far. I don't think this is a human ghost.
The chance of obtaining evidence without having to sit outside in British weather... how could I resist?
