Lights in the sky above the clouds doing patterned flying

My 7 year old son first saw the lights in the sky when we were driving west on I-96 between Brighton and Howell, on our way home to Howell. He said there were 4 lights dancing and meeting in the middle and then spreading out, each time getting farther away from the center. He pointed to it and his sister also saw this. I was driving but managed to look a few times and also witnessed what he saw. I could not answer him when he asked what it was. It seemed to be either lights from above the clouds or lights shining on the clouds from below- I couldn’t tell.
