A Pedestrian But Nonetheless Most Unusual Dream

A bus stop. A typical bus stop on a busy street with five people there waiting for a bus. Two people were standing and three people were sitting on the wood and concrete bench that was situated next to one end of the pole the bus stop sign was attached to.

I do not believe I had ever dreamed about a bus stop before. 

The memory of the dream isn't very clear and I did not write down any immediate notes when I awoke from the dream, which I usually do.

All I'm sure of is I was one of the people standing behind the bench waiting for the bus, and I was looking down the street as if the bus was approaching.

The other people at the bus stop with me had indistinct faces, almost as if they were department store mannequins with little or no real features.

The bus approached and seemed to be brightly lit inside, as if there were floodlights pointed up and out inside the bus.

And that's it, that's all I remember.

I hate riding the bus, so I wonder what sparked the dream?
