well this happened when i was about ten and im 16 now.At that time i shared a room with my sister.It was night time and for some reason i looked out my window and saw maybe 4 rings of circles.Each one contained like 5 bright whitle light balls.They were right outside my window about 14 feet in the air and a couple feet away.They hoovered there for quite a while.i dont know why i did not go outside and look at them from underneath or try to trow something at it or take any pics.neither did i tell my parents.i also told my sister she looked and got scared.she was 12 at the time.maybe a drawing would better explain it.you ask for a background they were in the space between my house and my neighbors house.
