Dreaming in Digital

I had a glimpse of someone's home life. Dean Winchester (from Supernatural) had a wife and two children, both of whom were daughters. The dream focused on his daughters the most, especially his youngest, as I remember her face clearly (she looked like [Ariel Winter]). In this life, Dean was still a hunter, but only for threats that were local or with range. His house had an ancient book, and the girls found it, learning the magic spells and speaking the incantations found within the book's pages. One of the spells was big trouble, as it unleashed chaos into the home (and maybe into the world). It was like they opened a gateway into the world. The two girls fought each other, playing the blame game, until Dean came in and tore them apart and passed them both onto their mother.
