nightmare

I was driving my care down a dark street and felt a bump and heard a scream behind me. I had hit and killed a man. People crowded around looking at him and back at me. At first I was horrified.. And I asked everyone around, is this a dream? ... Am I dreaming? Everyone answered with a no, or didn't answer. But I figured out I was dreaming, hopped back in my car and drove away, woke up shortly after.
