It was late afternoon on a Sunday and I was about to entre the drawing room from the kitchen - which was situated across the hall. I had a tray in my hands and so was moving carefully. i was just about to step into the room when I saw a fire ball come in through the front window - it passed through the glass! The ball, which was about 3 inched in diamiter and seemed to be spinning, bounced off the opposite wall - came back to the wall near the window it had entered by and then exited by a window at the back of the room.
I could not move as I watched it move about the room. There was no sound. The temperature in the room remained the same.
What was it?
Where did it come from?
