"Blade Runner" ... Was Decker (Harrison Ford) a Replicant .....?

in the original version, it is never implied that Deckard was a replicant. But in the director's cut, Ridley Scott drastically alters the film (his director's cut of Kingdom of Heaven is the best example of him entirely reconstructing a film). At the end of the original version, Deckard finds a unicorn origami in his apartment, suggesting Gaff had been to his place and could have killed Rachel, but didn't. In the director's cut, a scene is inserted early on where Deckard has a random dream of a unicorn, thus giving the final scene an entirely different meaning. Now the ending suggests that Gaff knew about Deckard's dream involving the unicorn, as if it had been an implanted memory. And Deckard leaves with Rachel, knowing he's a replicant.
