Dreams

Dreams. Are dreams real? I often ponder. because if dreams are real do the people in my dreams really get hurt? I get all sorts of dreams from happy ones to sad ones to out right depressing ones where i see my best friends die. What does that mean? does it mean i'll see them die? i'd rather not see them die. expessually if they die in the way they do in my dreams. but i would like my happy ones to come true. like the ones of my dream house. witch is a cottage with acers of land surrounding it full of horses and all sorts of animals with a forest all around it for me to go explore. i quiet like those dreams. or the dreams where i live in Disneyland those are good ones.  . . .but. . .then i wonder if dreams have a meaning. . .if they do what do my dreams mean?
