wow that is a really creepy story Yari!!!
i have a kind of similar one...my neighbours at the cottage were a lovely Irish couple in their 70s...well the wife passed away and when her husband was at the cottage a month or so later he saw this one butterfly that was always around him when we was outside...well he grabbed his camera (not digital) and put a new roll of film in it and went outside to take a picture of the butterfly...he took alot of pictures and then finished the roll of film that weekend and he heard the roll rewind when it was done....well when he opened the camera to take the film out there was nothing in the camera!! it was empty!! and we know for a fact there was film in it...his daughter and i were standing right there when he put the film in!
