Dream Interpretation: Get on the pony, Pop!

This morning my father wrote to me:

Are any of your new friends good dream interpreters? Last night I dreamed about you. We were walking up ninth street, in Alton [Illinois] at the stopsign where it becomes State. The hill was steep. We were out in the street, not on the sidewalk.

You were bareback, laughing. I was trying to figure how to get on behind you when I woke up.
