I had just finished watching a movie and I layed in my bed and put my head phones on. There is a window right in front of my bed and I looked out the window because I notice mars and a few other stars and thinking about how crazy bright mars looked right now. As I'm looking at it I see a white light with red and blue lights blinking on it flying by. I thought it was just a plane but what really caught my attention and made me get up and run to the window was how fast the object was moving. I have never seen a plane or anything for that matter move that fast before. Also what I thought was odd was how big the light was. At the size of the light and the distance, usually if it was a plane you should be able to see some detail at that point. Like oh okay, I see the blue and red strobes on the wings. But nope, it was just a ball of light. I watch it go behind some trees, still going very very fast, and as it emerged from the trees I noticed a smaller white light following it at the exact same speed. Then all of a sudden just before it flew out of sight, I noticed the two lights were connected and that what I was actually looking at was a huge black triangle craft with lights at the points. This freaked me out pretty good and I think I almost had a panic attack. As soon as I lost sight of it I ran downstairs and outside to try and see it, but It was completely gone. Which is also weird because in the 20 seconds or so it took me to get downstairs, even if it was really far away it still should have been in sight. But it was gone. I was pretty freaked out after the more and more I thought about it, but also cool.
