I had a dream that I was riding in a car with some people I know, and at the last moment a car in front of us swerved to the right, and there was a guardrail there and we couldn't avoid hitting it and flying over.
I didn't know how far the fall was, but in my mind I was thinking to myself not to tense up, and just wait for impact. It seemed like I was waiting so long for impact that I knew there was a very low survival rate. Then I started to think, well, hopefully this is just a bad dream that I need to wake up from, and then sure enough, I found myself trying to wake myself up, and it worked. It was weird, because for a short time after I woke up, I actually questioned if it was in fact a dream, or if it wasn't and my mind was tricking me into believing I woke up to avoid the reality of my inevitable (and soon to be) death.
Maybe this is still part of that trick, eight hours later.
