I choose Crossing the Red Sea and Immigrant Hostel.
Ideas: The migration is purely a physical journey. However, to some extent it's involved the commission to emotional journey and also the historical journey. In CtRS, this physical aspect is shown right in the title 'Crossing', a verb, that evokes a sense of change and moreover a journey that requires actions. (sorry for this awkward expression). Besides, its historical facets are reflected through its allusion to the Jews' iconic migration and the Polish's refuge that remarks a turn in their own history next to the signpost of disastrous War World II which is also the catalyst for this migration. In regard to their emotional journeys, we can't omit the healing brought about by the sea personified to spread its marvellous breath bandaging any wounds and anguishes.
Destination:
physical: to a 'Promised land' with a new life
emotional: get relieved from the traumatized incarnation
historical: a new page in their own history as now they become Aus-Pol.
To complete the idea of a journey, we need to mention its unpredictability ramification as well as its uncertainty. Here, in Immigrant Hostel, the migrants are trapped like birds (you should get some quotes as instances for simile) who know only one thing: they are powerless. Who tells them about the next change? Noone. Who gives them a cue for a positive change proceeding? No one...well, maybe because there never will be any positive change at that very time, it seemed.
Basically, a journey's destination can be an abrupt halt, a predicament it is but journeys are at times unhandlable.
I don't do Rabit Roof Fence but 'Whose life is it anyway?' by Brian Clark.
Cheers.
