From the Aboriginal tale creation:
The Dark Land was called Il-ba-lint-ja. Ka-ro-ra spontaneously appears laying at the pole (the stretched to the Heavens) asleep.
He ate when he was hungry and only after he satisfied his hunger did he realize he was lonely. (Survival first, then family)
He dreams of a bull-roarer who then becomes his newborn son. (The world was dark, but his colorful Dream leads to birth) He appeared in his armpit (metaphor for needing to hold and care for him). Then he sang him to life (metaphor for the nurture and care needed for a newborn).
He continues to dream of more and more sons and (subsequently) they appear after each dream.
