You 'exist' within a virtual reality because all of your external really real reality is altered by your own brain's internal mental software to fit inside your skull. Since really real reality isn't inside your skull, what you perceive there has to be virtual reality generated by your brain's mental software.
Video games, training simulations, "what if" research scenarios are all 2-D. Depth is an illusion generated by the software.
Now say you climb up to the Observation Deck of the Empire State Building (or equivalent) and take in all of the vast external landscape spread out before you. Now clearly that volume of space you see cannot fit inside your skull, yet that's exactly where it is since 100% of your really real reality is literally now inside your skull but as virtual reality. Everything external to your skull is perceived and filtered to fit comfortably inside your skull. Just like in a simulation, the dimensionality is transformed. Left-right and top-bottom are compressed to fit and depth is again illusionary. Your external world maybe 3-D but your perception is 2-D - just like any other virtual reality …show more content…
There has to be a loss of data in this compactification of a large amount of volume thrust into a tiny volume (your skull). Lots of stuff gets left out. So in fact there might be relatively little similarity between the really real reality out there and the virtual reality inside your head. It's like saving one in every ten letters that's in the text of a book or other document. It's the same with any simulation. There's never a one-on-one correlation.
This concept of virtual reality all in the mind is also nicely illustrated by the fact that you dream. Your dreams are internal to you. They are virtual reality. Your brain's mental software can create highly, very highly realistic dreams and dream scenarios. And as with the case of the translation of a vast external reality shrunk down to fit inside your skull, your dream landscapes are mini versions of what would exist, if they exist at all, 'out
