Parking
I don't remember much of this dream, but me and Yu Lee were in the car and Yu Lee was driving us somewhere. When we got to our destination it was difficult to find a place to park but eventually Yu Lee spotted somewhere.
She pulled over onto the "space" which was a paved area right next to a pond. The surface was paved in small, dark concrete tiles and was inclined gently towards the edge of the water, and was just about wide enough to fit the car on.
As soon as Yu Lee had pulled onto the space the car started to slide sideways, and in a couple of seconds the car was in the water, sinking towards the bottom of the surprisingly deep pond. We managed to get out and swim for the surface and I was telling Yu Lee how stupid she was for thinking that was actually a space.
