I think my imagination is broken.

When I am on the train, I plug in my iPod and play a very trival but amusing mental game... "how would I make this song into video clip?"

This gives me 3 1/2 to 5 minutes to dream up ridiculous scenarios involving submarines, love stories, great atriums in space filled with choirs, robots on quests or aimals made of lego.

But recently, all of my musical daydreams have featured trains, train platforms or freaks I see on the train.

Perhaps I need to get out more.
