We lived a few hundred yards from an ancient Aunt, who was a bit spiteful, so we didn't visit much. One Sunday lunchtime, our big mirror in the hall 'lifted' off it's hook, and smashed to smithereens on the floor. Puzzled, as the hook was still firmly in the wall, and the chain on the mirror frame was intact - in fact the frame itself was fine - we had to start cleaning up. The mirror was an antique, and came from my old Aunt's family. About half an hour later, the phone rang, old Aunty had died suddenly half an hour previously!!! I guess she didn't like us having anything of hers then....
When I was at college, my friend and I lodged with a family, and had a seance one evening. A stupid thing to do really when you are 'unguarded'. Later that evening, as my roommate and I prepared for bed, (we stayed in a downstairs room), everything flew off the mantlepiece and smashed, then our french windows 'blew' open! There was no wind, our main door was closed!
We went to the cathedral the next day, and explained what happened. The clergyman asked us what the messages we received were, and we told him an odd name kept cropping up. He went into the library, and it was the name of something in the demonology book. We were exorcised, and our lodgings had to be 'cleaned'. Never meddle with seances!!!
