It was 4 balls of light total. But either one would have had to divide into lights or the lights and other lights were fast. And i mean fast. I was in Schaumburg on higgans next to forest preserve and then within seconds the one light became two and three. And we went under an under pass. And within seconds the one light was miles down the road and the rest were gone. I saw the lights again on higgans and Arlington heights road and within seconds the one light was accompanied by another and another until there were 4 They made shapes. The 2 lights made lines and when there were 3 the lights made Triangles and when the forth light came they made a perfect rectangle in the sky and I mean perfect and they made all these shapes within maybe 1 minute. And the strange thing was that it was cloudy outside and then it just vanished. It was there one second and gone the next like it never happend
