I was just watching the girl and her Mother explaining their paranormal story. The first thing I noticed from looking at the photo of the house was that it was very close to a large pylon. Could that have explained things like the strange sensations, the toys moving by themselves etc?
I am personally very open to the idea of ghosts and poltergeists but still try to find rational explanations first. My Dad once told me not to delve into the paranormal as it is likely to open a door. Incidentally, when I was growing up I really wanted to be a Paranormal Psychologist.
