I had an odd one a few weeks ago, wrote it down because I think it would make a good short story.
In short: I was in a car that was forced off a railway overpass by a truck (stolen, driven by kids), which crashed onto a train and killed the driver. I felt incredibly guilty, and kept replaying over and over in my mind how I could have done it differently, until the replays seeped into my dreams (dreaming abou dreaming is pretty odd too). Then one time, in the dream dream, I was able to go round the truck but had a collision with another car. When I 'woke', this is what had happened, I hadn't hit the train. But another man had died in the other car. So I kept 're-dreaming', changing the past a little at a time, until I wasn't badly hurt, I didn't kill anyone else, and the only people who died were the kids in the truck (who went off the road after trying to hit me). I was trying to figure how to save them, but there was a physical cost each time I changed the past, and I wasn't sure I could do it. That's when the alarm went off.
