"All I can say about this is somebody has watched the Matrix or the Truman Show way too many times for their own good."
Maybe you just haven't watched them enough.
If everyone saw and perceived completely different realities to one another, we would never know.
For example: If I'm standing in a field with Kharma, my reality and my brain could be telling me "You're in a field with Kharma." Kharma might be standing in the middle of a City with me at that same time. The only reason we wouldn't be able to tell each other the differences is because our brains can only perceive things in the way that we see them or the way that we are supposed to see them. If you tell me that a street sign is red, how do I know that it's really not some other colour and the only reason I can hear you saying that it's red is because that's the only way I can perceive it?
