Cities in the Astral

I ran into an astral being who appeared to me as a young human male. We spent a little time demonstrating what I could do so far as far as floating/flying. I showed him that I could lay on my back and steer myself in any direction, even up over and down, feet first or head first.

He politely watched and seemed satisfied with my ability. He showed me a new method of travel in the astral or dreams. He became a wave of something between liquid and electricity and sound waves. I was able to copy him and transformed like I would to become an octopus but I became an energy wave and shot forward fluidly. It was something like the way the front edge of water pouring out of a bucket as it moves across the floor. It is hard to explain.
