How many of you have had a dream of the end of the world?

Ok I know it may seem crazy but I have had a dream of the end of the world in my dream everything was becoming so chaotic where people kept freaking out I could here people screaming in the distance children where wondering around without their mothers noire fathers crying and then all of a sudden there was a bright light across the city and a giant wind came hurraling tords everyone in my neghborhood and they all went flying into the distance I could see people being killed by being thrown into power lines and some getting cought into fenceing and being torn appart and for some reason I ended up laughing at all of it and no matter how hard I tried not to I wasn't in control but as I was in the midle of laughing I woke up panting and swetting what does it mean. anyway have any of you had a dream about the end of the world sorta simaler to mine
