A big oval light is moving in diagonal, suddenly changea direction e move in horizontal. After 1 second it vanishesI was driving in my car, the route was desert. I saw a light on the horizont, over me. It was big as a street lamp (almost three quarter of the full moon). I saw that the oval light was moving in diagonal, so I raised my eyes, thinking that it was a falling stars, but it was bigger, slower and suddenly it changed direction. Instead of in diagonal, it started moving in horizontal, and after a second it vanished. My first reaction was the cry, I was a little scared. The day after, to have a confirm, I asked to my university friends (I'm a doctor in sciences of communication and I'm attending a master of Journalism), and one of them told me that he too, the night before was in a car with a friend, and saw the same thing!
