We have a four story house including the cellars, and even when it's just us in the house on the very top floor the lights get turned on, sometimes the taps and occasionally sounds like someone is having a dance up there. We also have things moved to the top of the flight of stairs from the ground floor, always something weird, always something that makes no sense and always something that's gone missing months earlier. I can't really find a rational explanation for it, but neither are we jumping on the poltergeist theory, we're kind of open minded about it and fairly relaxed now, having frisked the whole house in a massive terrified freak the first few times.It's only been quite a recent thing in the last few months too, so wondering why that is before that the house was very still.
