Having to do what one doesn't want to do, and at the same time wishing to do what one is not able to do, might feel like some kind of living between the hammer and the anvil. Hating the everyday, and as if this weren't enough having all those damned dreams and wishes out of which much of that disliking gets even more powerful.
And that was the main thought behind this shot - just a try to superimpose the "duty" and the "wish" in the sense of a dichotomy. It is a triple exposure taken from the window of the train.
