explains your theory better. apparently here we feel a lot like that. I also often believe to live in a simulation
It basically goes like this:
There will be a day in which technology will improve so much that we won't be able to distinguish videogames/virtual stuff from reality.
Thus, the question shows up:
What if we're already living in a simulation?
Maybe, some "players" are controlling us and every single thing we're experiencing is because they want us to.
Also, there might be MANY/infinite simulations and that might be related to parallel universes.
Still, the mystery remains:
"What's the original world and YOU?"
Just like the movie, Matrix.
If you're interested in this topic I highly recommend you search on youtube "elon musk joe rogan simulation theory". It'll blow up your mind!
