When I was about 15 I was at this sailing camp in North Carolina. Me and a friend there were in good standing with the sailing staff, and our counselors, so we were sitting at the end of the pier (a *really long* one I might add) at about 11pm. It was just me, my friend, and two other counselors. They were up in the racing tower, we were sitting down below it.
Anyhow, we were just lying there, looking up at the stars, when I eventually pointed out two in particular. There were two "dots" that looked exactly like the stars around them, but they were moving like a fly or a gnat if your will. They didn't cover more than 2 - 4% of the entire sky as we could see it, but they were moving around rather quickly. We must have watched that for about 15 minutes, and as we were leaving the pier, it was still going on.
I never really thought much about it after that, and I still don't. I just know that the sources of those objects were most likely outside the earth's atmosphere, and truth be told, I don't think anyone can answer what those two 'things' were doing dancing around in the sky.
