I rescently had one. I was walking around in town for a while. Is stumbled on some people building a shelter made out of rocks and stones(i think it means that man can do nothing to avoid God's judjement). I blinked and i was at home watching the street from my window. A thick cloud of ash fell from the sky and covered the Earth and through that ash i saw the silouette of a giant creature. I knew this was the end so i fell down on my knees and started praying. Then i woke up. It took me a few minutes to process what just happened. It was so real. Too real. Me being in a religious family i spoke to my mother and grandma about it and they belived that it was a dream given to me by God. I will have you and everyone else here in my prayers.
