I asked my bf the other day about the weirdest thing that had ever happened to him. He said that a few years ago he was working in a reclamation yard and there was a skip full of stuff that appeared to come from an old dear's house, among which was a massive rusted metal key. Knowing his friend liked collecting old keys, he took it to him. The mate hung the key on a hook on the dresser in the kitchen. The two friends had been standing chatting for a few minutes (joking whether the key had come from a castle or something, given the size and apparent age) when Steve said he noticed in his peripheral vision that the key was swinging - but only to one side. After watching it for a while, he took a piece of cotton (why cotton I don't know) and held it up to the hook. The cotton started to twitch and follow the key, flicking up to one side only. His mate thought he was doing it deliberately, so he took the piece of cotton, only to be so freaked out at the movement that he stopped doing it. Steve then held the key to stop it moving and from that moment on, it never moved again. He said he reckoned it had been swinging for about 10 minutes. I thought it was a great story, well worth re-telling. Any explanations? Magnets or something?
