I dreamt that I was in a vehicle about the size of a duck boat.  The top half was clear, enormous, plexiglass bubbles forming a roof/enclosure the uneven shape of a puffy cloud.

My dog, Sunday, was driving the vehicle and I was in the passenger seat.  The plexiglass back of the vehicle was filled almost to the top with cartoon dogs of all sorts, but these cartoon dogs were three dimensional and alive.  There were so many they were stacked high and pressed up against the plexiglass bubbles.  My dog was a real dog, not a cartoon.

We were driving from normal surroundings towards a black void in which I knew was danger and evil.  The dream felt like a nightmare throughout.
