I may have told this before. About a year ago I was sitting at home with my dog, late at night, with some scotch. My wife had gone to bed. I heard some "hissing" in the back yard. I noticed my dog beginning to shake. I got up and saw a bell shaped balloon like capsule in the back yard and heard Christmas carols being sung from the inside. As I approached my dog went the other way into her hiding place. As I got closer to this thing it began to get smaller. Then smaller and smaller as I approached it. When I got to the spot where this things was it was gone. The next morning when I tried to explain to my wife what I had seen she never said a word-just looked at me.
