Stagecoach surprise

I had a dream the other night. I was in the old West riding in a stagecoach. Suddenly, a man riding a horse pulls up to the left side of the stagecoach, and a riderless horse pulls up on the right.

The man leans down, pulls open the door, and jumps off his horse into the stagecoach. Then he opens the door on the other side and jumps onto the other horse.

Just before he rode off, I yelled out,"What was all that about?"

He replied,"Nothing. It's just a stage I'm going through."
