Twice I saw a light zoom from my tree, once to a series of branches, the ground, and it disappeared both times.It was about 12:30 A.M. and I was listening to music on my MP3 and looking out the window. I was sitting near the window (about one foot away) and facing the window. All of the sudden I saw a rectangular shaped light fly from directly above my head from the roof to a tree in my backyard. The light was about six inches wide and nearly one foot long. The roof was about twelve to fifteen feet tall. The light moved in a straight line from the roof to the tree (about thirty feet). It moved about sixty feet in about one second. I looked up in the tree to see if anything was there. I did not have a clue what it was. At first I thought it might have been a white owl or bird although there are not many in my part of the town. This is because I live in a suburban area. I did not see the light up in the tree after that. About fifteen minutes later I saw the same exact light from the same spot zoom into the tree. Then, unlike the first time I saw the light, this time the light went from one branch over to the next parallel to the ground. A few seconds after that it went from that branch to a lower branch about two feet beneath it. From there the light seemed to squiggle down to the ground. When it hit the ground it immediately bounded twice away from my house and towards the road behind my house. Each bound was about forty-five feet in length. Once the light had bounded away from my house it seemed to disappear after it hit the ground on the second time. It landed in a part of our garden where we had rocks as our landscaping. I never saw the light resting there and I never saw it move from that spot again. At this point I was pretty sure that it was not any type of animal that I have ever heard of.
