Crazy dream...could it mean anything? Or was it just a dream?

Ok, I dreamed that I died. And was present through the entire process. I was driving my car back home from visiting a friend, it was evening so the sun was glaring. I was approaching railroad tracks, not paying attention. The crossing gates weren't down, nor were the lights blinking with the bell ringing. And then all of a sudden this train roared in front of me, but it was too late for me to stop. I tried to swerve but plowed into the train anyway. In my dream, I could hear the metal twisting, the gl breaking, the train's brakes screeching. In past dreams, I've "felt" pain, but I didn't feel any as I plowed right through this train, yet I knew I was dying, and I saw the darkness creep over my vision as I died. The next thing I saw were rescuers pulling my mangled body from the wreckage, and the damage it had done to my face. I had numerous holes in my head, including a large one on the bridge of my nose, and the left half of my jaw was just...gone.
