3 lights forming a traingle

I noticed a really weird moving light off in the sky. It was acting fast and erratic and all over the place. So i went inside and made my daughter go for a walk with me to check it out. She seen it too. After we walked around the block and got back home, she was scared and went inside. The whole time the lights were getting closer and closer. But after she went in, they disappeared for a second. So i layed back on my car to watch for more shooting stars. And that is when I seen it above me. But this time it was 3 lights right above me. And in a triangle formation. But inside the lights it was darker than dark. Then they changed shape and then I ran inside.
