Well from my perspective, the point your missing is, your never looking at anything solid as to say your seeing anything different than me. For example, I have friends who hate milk.. I love milk. The milk is the same, yet totally different perspective on it. The same goes with visuals. What you see is nothing more than what your mind is creating and furthermore how your mind interprets what it just created. We can be in the same spot staring at the same thing and verbally express we see the same thing, then turn and walk opposite directions and see totally different things. Why, because there was never anything more to see in the first place then what we were at that moment. If everyone in the world so the same thing as everyone else all the time, I would then be concerned if you started seeing different things lol. Fortunately we are free to see whatever we can convince our minds is there. There will never come a time when space is too limited for new things to enter your perspective. Technically speaking, when are you ever looking at the same thing twice
