The characters in the dream were Will Smith (Will Smith), James Avery (Philip Banks), and either Nia Long, Daphne Maxwell Reid or Karyn Parsons...or a composition of all three.

Here's the premise of this dream as far as I'm able to understand: Will Smith was learning some sort of important life lesson. He was sent back to the future back to the time of Nazi Germany. James Avery played Hitler, complete with moustache and the "composite woman" played a woman who Will trusted and loved, but betrayed him (Is "doupleganger" the appropriate word?)

James Avery wore make-up to make him look white but made it apparent that it actually was make-up.

It was taken place inside the mansion.

We pick up on the dream where Will Smith confronts "Hitler". "Hitler" becomes frustrated with Will and storms out of the mansion. The woman who Will was so close to gives him an evil look, turns his back and leaves.

Will becomes very mad and leaves to another room.

At this point I turned my head away.

Something dramatic happened. I'm not sure what. "Roll Out The Barrel" was playing at radio clarity. I looked back to the show. Will Smith exited the house with a smoking gun. He either shot "Hitler" or the woman. "Roll Out The Barrel" was now playing at crystal quality.
