#1, you're brought into this world, not knowing anything about it. This means that the prison can mold you into however it wants in this world.

#2, you're forced to work for pieces of paper for no reason other than "Well that's what we do here." It takes energy and time out so you don't have time to question your reality

#3 many consistencies within NDE's and altered states of consciousness and online anecdotes and multiple people seeing that we're trapped in a simulation

#4, the love in NDE's are forced on the person, with no free will of the person to say no, I don't want this love bomb, it comes in too quick.

Believe what you want, not forcing anyone to believe in this theory but the stories out there are enough to make you suspicious of reality.
