Short Stories with Tragic Endings

I am on a Gran Turismo track from either GT4 or 5, I'm not sure. I am in a 1st person view
of a car from the PSX game "Twisted Metal II" and there are other cars similar to TM2 cars
but they are not any of the actually cars in the game. Suddenly, the final boss of TM2 comes
out of the pit-stop and starts attacking me. I thought, wait, he shouldn't be on this level! But it
didn't clue me in to it being a dream. I somehow convince him to attack my opponents,
the other cars, and after he attacked the first car, the dream ended.
