dolphin's dreams

I woke up in my bed when I found I had trouble moving. I tried to move and ended up flying out of my bed using my stuffed dolphin. I flew outside in the morning light. I noticed my shadow was that of a dolphin but when I looked at my body it was still human. I saw a freight train moving along. I like trains. I put my hand behind my back to summon a dolphin. I felt it's beak and turned around to see a nice full size bottlenose (about 8-10 feet long.) I tried to grab it's dorsal fin to ride it but I couldn't move fast enough and it ended up flying away. I turned my attention to time control. I saw the train let to a small city with some cars on a road. I first tried pausing time and fast-forwarding time which both didn't work. Then, I rotated my forefinger to rewind and fast-forward time. All of the cars went backward then forward respectively with the direction I spun my forefinger. I was trying to think of my next task when I woke up.
