I was in a trance festival in Elvas, Portugal 2011,I became aware of the UFO in the photo after reviewing the picture on the screen.At the end of the year when I was at a gathering of friends, one friend said me he saw lights in one of the last nights of the festival, over the dance floor.Until then, he did not know about the photo that I picked up in the morning of the festival.Despite the photo, I have not seen any kind of phenomenon.I wonder what you have to say about the picture.
