Neo: “Right now, we’re inside a computer program?”
Morpheus: “Is it really so hard to believe? Your clothes are different. The plugs in your arms and head are gone. Your hair has changed. Your appearance now is what we call “residual self image”.
It is the mental projection of your digital self.
Neo: “This isn’t real?”
Morpheus: “What is real? How do you define “real”?
If you’re talking about what you can feel, what you can smell, what you can taste and see then “real” is simply electorical signals interpreted by your brain.”
