Someone versed in "our" (westernized American) culture might be able to see a ghost...they'd decsrbe that experience (I heard a voice cooing and felt a cold wind and the lights went on and off and then I saw the shadow of a woman on the wall) to someone and the other person might say "Oh, you saw a ghost."
Someone versed in Aboriginal culture might say they saw a person out in the desert, wandeirng and singing and they looked sort of bhazy and sparkling and when you turned your head a certain way they'd be there and when you looked another way they would not be...and someone would say "Oh, you saw someone in the dreamtime."
Ursula LeGuin's novella "The Word for World is Forest" seems to utilize Aboriginal mythology for the premise of the world the story is set in.
I teach a sewminar on Australian cinema and we always begin with Walkabout--good film to experience at least a subtle treatment of this idea.
