I once had a very vivid and strong dream where I tended to lightspeed-run backwards through the evolution of Earth, stopping for short seconds here and there to see different steps of human and other evolution, seeing the trees shrink and then disappear, then I run out on the ocean, to my far right I see this giant rainbow-fish creature that is made of a rainbow body, fish head and fish tail, jump out of the water whale-style, then all of a sudden I take off, up into space where I see a tiny space shuttle, I fly into it, in it there's a male and a female body seemingly asleep, it's all very simple and white inside the tiny shuttle, and small, and I zoom into the male body, wake up and become him, try desperately to look for something in the tiny pod but I can't seem to find it, then I feel like I'm suffocating, and the last thing I see before I die (wake up in real life) is the Earth through a small circular window in the shuttle.

But that also suggests a linear time perspective, all though backwards.
