Considering PKD's obssession with epistemology and memory, the nature of reality, etc., I think there's more than that basic level here. He frequently asked the question of how we know anything about anything ... even our own past, memories, and personality. That was something very much retained in the film, I think; and, like his books, it is made to reflect on our own experience and make us question some very basic things about being human that we take for granted....
