whats that feeling

what is that feeling where u suddenly just think. 

i feel like id be alone in this but ever since ive been a kid, ive been hella thinking, like TOO HELLA. personally, i believe in God but sometimes i get a weird feeling that the world we live in is a simulation. or maybe i mean the world i live in. cause sometimes i feel like the life in living isnt real. and these people arent real. what if theyre just npcs that are put to test me. sometimes its like a truman show way where everything is fake. but aside from the 'show' part. what if im just an experiment. idk lmao HWHAHAHHA
