well i was watching the wizard of oz to do it as part of my related material... but if you look at the characters more closely... like the 3 farmhands are the lion, tinman, and the scarecrow... and their personalities are also personified, the wicked witch of the west is the bike riding freak wanting to take toto and the magician dude is like the wizard, while her aunty is like the 'good' witch if you look closely and compare the characters..
and also the way in which the 'normal life is like in black and white' while the 'imaginative aspect of the journey is in colour'...
the yellow brick road is a physical journey in itself obviously...
maybe paying attention to the song 'somewhere over the rainbow' in the first 30mins or so kinda reveals something about the imaginative journey im not quite sure... i watched like the first 30mins of it and gave up taking some shitty notes on it.. like pay close attention to the lyrics of that song...
well dorothy suspends disbelief by going on such a journey... blah blah blah you can go on for ages with only the first 30 mins i mean its like what you pay attention to...
her aunty says something about dorothy going to a place where she wont cause any trouble... i dont know the exact quote but its something like that and then dorothy repeats someplace where i wont cause some trouble [i think!!
]
oh well... i hope that helps..
