When I was about 6 or 7, I was sitting on the couch of our old house during a storm. From the outside, a white-hot glowing ball about the size of a softball came through the baseboard, rolled across the floor, and rolled through the baseboard on the other side of the room and disappeared. I have read that it is a rare thing that people witness this, but i know what I saw!
It sounds like ball lightning to me. Im glad nobody was hurt.
