I dreamt I lost the car.
I was going somewhere when I found that I was walking in front of the trailer, instead of being in the car. At the time I found out, I was talking to someone about the contents of the trailer. I don't remember very well but it was probably a motorcycle and he tought it was cool.
Of course, I had to go back and fetch the car. In this dream, the car was small and dark metallic blue. I think I found it, too, but the dream was not very clear on how I went back for it. In any case, as I found it it was still running.

That was a nice and silly dream. I'd be interested in any interpretations that you may be able to give, but I can't guarantee I'll take them seriousl. ;-)
