Several years ago, when I was at summer camp, I was lying in my bunk bed in the cabin unable to fall asleep at 3 am. I glanced out of the window into the woods and I say several balls of white light floating in the air. They appeared to be the size of basketballs. They would appear near the ground, float up a few feet, dissappear, and then re-appear several feet away. I watched for a few minutes and awoke my friend who was on the top bunk. We both watched them and dared each other to go outside of the cabin and walk up to them. Utlimately, neither of us got up the courage to investigate and the lights went away in about 30 minutes.
