The fact that our brains filter out most of the information and what you see and hear is actually a hallucination that your brain creates based on the information it receives really adds to this version of simulation theory.
Like, our brains create their own version of reality as it's happening rather than just showing us what our eyes see, etc.
Its something to ponder. Reality only exists because we perceive it.
when you take a low mushroom or LSD dose your brain stops filtering stuff out, that's why you can see how everything is vibrating and the vibrant colours that are normally dulled right down, it's why you can feel every single part of your digestive system and your kidneys and liver and everything else working away that you normally block out, once you take enough though it's too much information for your brain to handle and sensory inputs get jumbled up, leading our brains to hallucinate things that aren't there or feeling colours and stuff like that.
Stuff like this is why Id have a difficult time following any organised religion.
The truth about reality is beyond human comprehension.
For a human to understand the nature of the universe would be like the bacteria living on our skin to understand the nature of humanity.
