When I was growing up I was at my grandmother’s house out in the woods, she had land on a hill so the sky was pretty visible and usually very clear at night. The stars were easy to spot. One particular night I was looking down her driveway when I saw the entire sky light up green. It turns out meteorites burning up in the atmosphere can turn the whole sky green suddenly, but I didn’t know that at the time and it freaked me out bad.
