Scooby Doo, where are you?

A few people, including Brooke and I, are in a camper van that is parked. It rocks suddenly as if something big smashed into the side of it or as if it was caught in an earthquake. Then it starts driving forward, even though no one is at the wheel. It rolls down the street out of control and smashes into a telephone pole. Then we are driving through a neighborhood looking for a house that is haunted. I believe it is the ghosts that took over the van and crashed it.
