I think life is a simulation. And the time when we're sleeping is the only time we're awake. Do you ever look at a texture and it seems unreal? And what if the shadows we see in our peripheral visions are the runners of the simulations. What if nothing is real? What if all of the "what if"s are real? And nothing we do matters?
But, on the other hand, it's real to us. Shouldn't that mean something? It's real for us because we're living it. It's our reality, even if it isn't reality.
Then again, I might just be delusional.
