It was late at night and pitch black, me and my friends were still up and we were taking pictures with our camera using the flash icon. We viewed a couple of the pictures and realized there was solid balls of light floating above us or next to us, it scared us and we decided to do some research then we found this website and noticed some of the pictures were identical to the balls of light we had seen on our photos. We want to find out if they are harmful or not? unfortunately we can not send pictures because we deleted them but if it helps there was a couple in the pictures roughly 2-3 and some of them were faint and some were very clear. Please let us know if they are harmful or not and why they are here.
