Dream of father, mother

I dreamed I was looking out of the kitchen window at my dog Alf, a black labrador who was laying in the grass. My parents came along behind him and my father was holding a brown kitten on a lead. They wanted our dog to play with the kitten and that's how it appeared, until I saw Alf catch the kitten's head in his mouth. I knocked on the window loudly and shouted. My mother started shouting in horror too as she could see what was happening. The next thing I remember, my parents were in the kitchen with me and I picked up our small black shovel and started banging it off of the wall to stop our dog from killing the kitten. Our dog released the kitten when he heard me but to my absolute horror, I saw that the kitten's head had been decapitated and there was blood.
