I imagined that I was underwater and bubbles were all around me. I was able to breathe underwater and I was just floating there, limp, relaxed, and happy. Then my surroundings changed/morphed and I was in a futuristic setting. It was a metal tunnel and I was in a car-like thing that moved on an electromagnetic track thing. There were wires and green and red lights lining the whole inside of the tunnel, too. (The type of lights that you see on machines such as printers, computers, ect.) The car-like thing was moving faster than a jet, and it was awesome.
