Who am I to Beleive I Can See Outside The Realms of my Limited Perception?

I was taking a nice, calm ride in my car on a Sunday morning and I started pondering the limits of our senses. I was looking at some optical illusions earlier and it amazed me how some shading and other tricks can make us see things that aren't there or completely miss things that are. Plus there are many studies show that if we are likely to completely ignore certain visual cues if not introduced to us at certain developmental stages of our childhood. We are so limited to our experiences and therefore, in our thinking and philosophy.

Then I started thinking that maybe everything I experience in the outside world is all just a part of me, much like what seems real in a dream is just our imagination running wild in our sleep. I was thinking all the people I know are just extension of my own psyche and it occurred to me that even those who have treated me wrongly are only parts of my psyche I haven't comes to terms with yet.

It make sound like a self centered theory, to think that the whole universe revolves around me and after all my blogging about how we're not the center of the universe. But what's so selfless about thinking that we're separate from each other? I think I'm more likely to act with compassion towards others and the environment if I think of everyone and everything as a part of myself. I can comprehend it being differently but truly, my mind isn't capable of seeing passed that. All my experiences are just limited sensory responses occurring within the boundaries of my mind's operating system.
