Haha, I'm sure this is a feeling is common amongst everyone else in the world. Needless to say, when you're confined in your own world of thoughts and emotions, and are experiencing life through your own persona, it would be quite hard to see everybody else as anything but additional features or "robots" as you like to put it. I admit, I used to feel a lot like that when I was slightly younger and more unaware of people around me. It...isn't the best feeling in the world, it can make you feel alone and isolated at times, as if nobody else could comprehend the kind of emotion you're feeling like you do, and it can also make you yearn for security and identity; it's quite a lonely feeling.
I've pretty much changed a lot from the way I used to be since I've gotten to know people and learned more about their life and obstacles. When you learn more about others, you start feeling as though you're a part of them; and there's no greater feeling than knowing you can actually belong. So I don't really feel that way as much anymore. From my experience, feeling as though you're the centre of the universe is like not being able to understand other people, therefore you're more confined to yourself. I could be wrong in some aspects, but it's generally the way I see it.
