The things we represent to you are imaginary. Most of us I'm sure are real people with delusions of our own.
I think if you want to achieve enlightenment, seemingly the buddhist concept of enlightenment, you must accept that your experience of reality is onlly from your perspective, and thus not think in terms of "your" as if we're figments of "your" imagination.
You are not wrong! In fact, I'm an NPC programmed to confirm your video game theory. Now that I told you, I don't have any other purpose. I'll shortly be deleted to save memory space. But wait! The designer of the game has a message for you: "To advance to level two you must first quit pot"(I, the messenger, am deeply sorry, but you want to win the game don't you? ) PS: Type "more money" without quotes for infinite ammounts of money. Hope I helped.
Yea this isn't very likely, it's a pretty egotistical thing to believe in a way, or just plain silly... but it could be true, for all I know right now I am passed out about to die and I am reliving my entire life, just like a dream, only to die in the dream, and consequently, in my actual life
Well, how could I be part of your imagination, if your imagination doesn't exist? Wouldn't that mean none of us exist?
OP, you've just described the philosophical ideaology of: "Solipsism! An epistemological or ontological position that knowledge of anything outside one's own specific mind is unjustified. The external world and other minds cannot be known and might not exist. In the history of philosophy, solipsism has served as a skeptical hypothesis." Here you go, a good starting point.
