The Oneironaut's Odyssey

Skyfalling
I was dreaming that I was in a room, like a plaster walled garage. Someone was showing me around with a couple others, there was this huge plastic great white shark in the room. I remember that the tail was all weird, like it hadn't been attached properly.. Next thing I remember is being on the border between atmosphere and space, extremely high in the sky as if I could see the whole earth.. There was another person with me, an enemy I think. It was somehow related to the shark room before. We were plummeting down to Earth, I was going to divebomb him or something. How did we even get this high?
