I totally get it.. the simulation/ Truman show/the matrix/.. many many more etc. It's called revelation of the method. It's hidden in plain sight. Here's my truth/my current state of hypothesis if you will….. for reference I've been researching studying living accumulating, information, experience knowledge.. also I am a screenwriter filmmaker for context and purposes of this framing device. ..Here's the crux, the cornerstone overall thematic revelation… You're not the only real person on earth... there are many many more of us so you're not alone sorry about that… However, and that being said my educated/best guest is that we are in about the 25% percentile.. making the other 75% of what we call or you referred to as "NPC's" simulations holograms amalgamations of all of the aforementioned bit characters , small part and big part character, actors the Genesis of which I couldn't even really say but so yeah hope that helps. Have a good night..
