Do Androids Dream of Electric Sheep? (1968) is the story of a bounty hunter policing the local android population. It occurs on a dying, poisoned Earth de-populated of almost all animals and all "successful" humans; the only remaining inhabitants of the planet are people with no prospects off-world.
The 1968 novel is the literary source of the film Blade Runner (1982). It is both a conflation and an intensification of the pivotally Dickian question:
What is real, what is fake?
What crucial factor defines humanity as distinctly "alive", versus those merely alive only in their outward appearance?
Keeping this PIVOTAL QUESTION in mind also helps to understand what seems to be one of the MAIN THEMES in the story.
Is RACHEL REAL?
Is JOI REAL???
Is the girl inside of the GLASS BUBBLE REAL or is she just another HOLOGRAM ... like SINATRA inside of his GLASS JAR ... or like the other REPLICANT PROTO TYPES that we see on DISPLAY inside of the GLASS CASES ... inside of what use to be TYRELL'S TOWER (before it was purchased by WALLACE).
DICK also wrote another NOVEL called UBIK where the DEAD or HALF DEAD can also still communicate with the LIVING:
Ubik (1969) employs extensive psychic telepathy and a suspended state after death in creating a state of eroding reality. A group of psychics is sent to investigate a rival organisation, but several of them are apparently killed by a saboteur's bomb. Much of the following novel flicks between different equally plausible realities; the "real" reality, a state of half-life and psychically manipulated realities. In 2005, Time magazine listed it among the "All-TIME 100 Greatest Novels" published since 1923.
And this is also what appears to be the case with the REPLICANT RACHEL who has the MEMORIES of TYRELL'S niece IMPLANTED into her.
When you're a being who's been created with the MEMORIES of someone else isn't that also a SUSPENDED STATE or a State of HALF LIFE or a bit like communicating with the DEAD?
Or do we even know whether or not the NIECE is DEAD or not???
Whatever the case may be, my theory is the GOLD COLORED VEGAS SETTING, which MATCHES the GOLDEN COLOR of the PYRAMID SETTING, which also MATCHES the GOLDEN HUE COLORED SETTING that we see in LA are all HOLOGRAPHIC IMAGES.
And when K enters the CASINO ...
that probably also PARALLELS the way he ENTERS the HOLOGRAPHIC GARDEN ...
only to find his TWIN SISTER there inside of a HOLOGRAPHIC GARDEN SETTING ...
where she proceeds to create still more HOLOGRAPHIC characters (kids at the BIRTHDAY party) ...
the same way as we see the other HOLOGRAPHIC images of Frank Sinatra and Elvis there inside of the CASINO.
And the thing that seems to BIND them together is the BEE that we see inside of the GARDEN, and the other HIVES of BEES that we see in VEGAS that swarm upon the hand of K.
Since there are no longer any animals or insects in this world (which have been destroyed by the RADIATION), that also seems to be an indication that VEGAS setting inside of the CASINO is a HOLOGRAPHIC WORLD and isn't a REAL WORLD.
And The GOLDEN HUE COLOR that we see also seems to be an indication of the same thing letting us know the area that we inhabit isn't REAL.
So the ANSWER to the QUESTION of WHAT is FAKE and WHAT is REAL would probably also be nearly EVERYTHING we see in BR 2049 is FAKE.
And that includes WALLACE and K's BOSS ... who are also FAKE HUMANS ... due to the way that K (and his HOLOGRAPHIC side kick JOI) behave in a much more HUMANE manner than they do.
Thus also placing them into the category of those merely alive only in their outward appearance, but otherwise pretty much also DEAD on the INSIDE?
Otherwise, how could someone who was still ALIVE inside order the DEATH of a NEW BORN being or order the DEATH of RACHEL and DECKARD's child???
