If we take the question out of the realm of philosophy and android ethics and into the purely practical sphere, then, no, androids aren’t having dreams about sheep of any sort. Well, most of them aren’t, anyway.
It’s one thing to look vaguely human and do prestigious work. Maybe your robotic self doesn’t even realize it’s not human, that you’re just a fictional character. But it’s really something to be standing on rusty legs in some backwater, tending cretinous electric sheep 24/7. Dreaming? You bet I do — of those wretched creatures kicking the bucket. I’m sick of it. Who needs them anyway? And it would be fine if they just stood around eating grass, but no, what they’re doing is a full-on imitation of frenzied herd activity. Give me a break.
There’s a monument here, too. To a writer, of all things. Someone writes a book, other fools throw together an android/electric sheep installation based on it, and my job is to stand here, attracting tourists? And they consider themselves homo sapiens? Half of them haven’t even read the book!
