Wicked scary dream about my dad killing me?

Last night I dreamed that I was home with my mom and dad, (not sure where my little brother was) and a friend who looked a lot like Juliet Capulet 0_o anyways she randomly fell to the floor dead, my dad was so angry because he thought I had killed her. After a while my dad came to the living room and said something about the girl and I yelled "But dad, I didn't even touch her!" to which he replied "neither did I" in that moment I saw a bloody knife he was holding behind his back, my guess is he had already killed my mother, he then proceeded to stab me. I was screaming mom, which was a futile effort and he kept saying "just enjoy life now." SCARIEST DREAM EVER. by the way my dad has never hurt me ever. helpppp.
