Who is our local expert on the Indigenous Australian people and the Dreamtime?

Last night, I became lucid in a dream where I was confronted with tall rocky cliffs. At first, I thought I was in Hawaii, and that I was looking at the Pali Cliffs. I flew to the top, and realized that I was not in Hawaii, but on a huge rock formation that was surrounded by a flat sea of desert.

I was joined by two young dark skinned boys. We talked about lucid dreaming, and they showed me a game similar to basketball, but with a crude heavy leather ball. I had a hard time playing because the ground was very uneven. I wanted to show the kids something fun, so I held the leather ball, turned it into a football, and then threw it off the side of the cliff. I spun it end over end, like a really bad throw. It flew out in a wide horizontal arc, and returned like a boomerang. I then unraveled it into a flat piece of leather, and folded it into an origami dog. I brought the dog to life for the kids to play with. It looked like Dachshund puppy, and it only lived for a few seconds before dying and turning back into a folded piece of leather.

I did not make any Australian connections at the time, but looking back at the dream, I believe I was on top of Ayer's Rock / Uluru. It looked slightly differently than it does now. It was spotted with snow, and slightly taller. The football boomerang thing, the landscape (except for the snow?), and the dingo creation thing all make me think of Australia. I think the two boys were indigenous Australian, not Hawaiian as I originally assumed.

The two boys knew I was lucid, and we had a conversation about dreaming. They seemed to be experts, and I felt like they were testing what I could do. I was showing them some tricks, and they were showing me a few things.

I don't know much about the dreamtime / Altjeringa, but this dream makes me want to learn more. Can anyone recommend some good books about the subject that are not too biased by new-age philosophy? I remember a lecture from an old art class in college where they showed us some Dream Maps. I would love to learn how to read these and maybe draw some of my own.
