Well, granted you may "like to think that," but is there one single, solitary, tiny piece of evidence that you might provide to suggest that it is more true that God is imagining us all (which makes you 100% unreal and 100% without any control over anything whatsoever), than that things might actually be pretty much how they seem?The real question is are we real? I say yes, because we are in God's "mind". I like to think that we're all just "figments" of God's imagination, except when God conceives something, it's actually real.
After all, in your scenario, you didn't originate your own thought, and I'm not originating my response to it. In other words, neither you nor I is anything at all, and worth, one must assume, even less. Enjoy that, if it makes you feel good.
