Huge bright object with no noise rose up out of woods behind my house!!

It was late at night around 11 or 11:30PM and I was sitting on my back steps off my porch having a cigarette and talking on the phone to my boyfriend. We got off the phone and I was finishing my cigarette when this HUGE thing rose up out of the woods behind my house with no noise but lots of lights spinning around the center of it.It was less than an acre in the back yard so however far that is, that's where it came from. It came up and out at an angle so I saw the bottom and then it straightened up and came across my yard and over the house. It was only on the tree tops (pine and pecan) so it was VERY low and made NO noise at all. I was watching and backing up to get inside at the same time. I wanted to keep watching but was TERRIFIED!!!! I ran inside and told my grandparents and they didn't know if they should believe me or not but the next day my grandfathers friend which lives across the street from him had been outside and he saw it too and said "it was so low and so bright that you could have found a needle in the grass"!!! so anyway that's my story. Haven't seen anything like that since but have had other things since childhood happen.
