... you don't believe in the whole virtual reality spiel?
[john really would rather not believe in the virtual reality, he hates the thought of his body being in a separate place from him. it's nothing he would want to bank on either, and it definitely doesn't reassure him in the slightest to think that none of this is really real.
just some kind of virtual reality which feels real in all the ways possible while his body sleeps... apparently soundly, but hopefully not- he imagines his body being experimented on while his brain is here in this place, accepting all this as reality]
