We used to live in a remote area of n. California in a new home. One night we heard a bouncing ball that seem to bounce in our bedroom about 6-7 feet apart as if two entities were playing. Our two dogs that were on the bed were fascinated as was my wife and I. The dogs watched the invisible ball like they were at a tennis match after awhile they tired of it and started barking at it. I never thought too much about it although I did mention it to friends and we all tried to come up with an explanation, but recently I have heard a lot of stories connecting bouncing balls and ghost,my question is What is The Connection?
