The worst vivid dream I have had to date is this. Flying a Spitfire in WWII a german fighter comes out of the sun riddles the plane and me with bullets. The plane goes into a lazy descending spin I can see but cant move and then under the instrument panel burst into flame and starts to burn me. As I get closer to the ground I see a Hay field complete with a wagon and hay bails. It gets closer and closer impact blinding flash dead black. I jerked up right breathing hard and my heart pounding and sweating, that was the worst vivid dream I ever had and it was like 35 years ago and I can still recollect that dream in my mind as clear as the night it happened.
