I dreamt I was in a chariot race holding on to the rail behind charioteer Spartacus.   I was looking back at my right leg which was severed but for one sinew keeping it waving in the wind.   I was annoyed that it was slowing us down with its drag.

[I think it was Ben Hur, not Spartacus, who raced a chariot, both as played by Kirk Douglas.  Regardless, in the dream, it was Kirk Douglas, as Spartacus, in a chariot.]
