My cousin Christian tells a joke

I am in Auvergne in the field near the family home. There is my father, my brother and Christian. My brother and I are children. The dream is set in the 80s. My father tinkered with a zip line with an electric motor. It is connected to a cable between a tree and an unknown point. At one point Christian tells us a joke about a cousin from the South who would have reincarnated in a dog. He told it seriously but I know he's joking. This is Christine, the daughter of Marie-Jeanne, my mother's cousin. I'm saying she must've done some serious bullshit to be reincarnated as a dog. I wake up before the end of the joke. We were all captivated by Christian's story.
