"During his investigation, Deckard learns that replicants are provided implanted memories, and he uses this fact to help Rachael understand the truth about her origins by quoting one of the memory vignettes that were programmed into her. Likewise, Gaff (Edward James Olmos), the mysterious police officer that has been following Deckard around throughout the investigation, seems to know about Deckard's unicorn dream when he leaves an origami unicorn outside of Deckard's apartment at the end of the film. The only way that Gaff could have known about Deckard's private thoughts would be if Deckard was a replicant, and that the unicorn dream was one of the standard memory implants that he possessed."
interesting read, here
