I'm doing it, but the only thing teachers are doing is complaining how its more imaginary!
Anyways, Dora's inner journey, finding the courage to move out of her fascist surroundings to be with Guido and live a less wealthy life. The main defining point for her is when she boards the train.
Joshua's inner journey is outside the film, he is retelling the story, in the beginning when Joshua was announcing hes gonna retell, everything is black and misty, dark and scary
Guido - he is the "prince charming" - carefree and giddy, then he undertakes an inner journey to survive in the camp and to preserve his son.
Dr Lessing - His innner journey is not affected by any external forces.
I think they are the main points.
