Tunneling through

From what I know, tunnel vision has two definitions:

One of which is physical (wikipedia) : the loss of peripheral vision with retention of central vision, resulting in a constricted circular tunnel-like field of vision
One of which is metaphorical (urban dictionary): Limited vision, as in seeing only your own point of view
(sources aren't very reliable but you get da jist.)

Anyway , I was just thinking, don't we have the massive-est tunnel vision ever. I was sitting at the back of the train and staring at the view of the seats and I could only manage to visually reach out to the blurry view outside the windows. 

Most of this is unsupported evidence (as i have learnt in uni LOL) but the only reason we don't feel trapped with our "tunnel vision" is because we have thoughts and imagination that take us to other fantasy places and subconsciously construct the world around us so we don't freak out about our surroundings (eg. we know if we walk outside our house, there is going to be the porch). I think im trying to articulate what I feel now. For example, although within my field of vision is only a freaking computer screen right now, my thoughts are what set me "Free" and don't make me feel trapped LOL freak this sounds so corny but you get me yah?

the more I realise these obvious kind of things, the more existential I feel, the more weird it feels because I feel like realizing these little things allow me to see the bigger picture of (something). Since a lot of the time, "reality" is grasped with sight, our tunnelly vision, much like a film reel, only plays a tiny bit of the picture(and our thoughts only make up a portion of the out-side the tunnelly vision). That is why (if i recall correctly) the red bull guy who jumped from 60km away from earth felt the immensity of the earth/"reality" and his own insignificance, and human frailty and blah etc. because in his tunnelly vision, he saw half the earth.

which brings me back to the same ole question, is there a better way to get a hold on reality? a way that I don't just take in what I see in front of me and the in-front-of-me view when I turn 180 degrees but to "See" the whole earth in action/everyone's lives at once, I guess id have to be omniscient. Also, if i close my eyes I can't mentally imagine another way to ground myself to reality, how do blind people do it, what the heck do they do.

Another point I wanted to make is that within our limited visual frame, this may be obvious but I want to look at this from a visual perspective, that who ever enters it most are probably the people who have the most significance in your life which is kind of no shit because if you are close to someone chances are you spend time with them and visually "see" them more. But maybe this can also be attributed to the fact that being present/in the vicinity of someone you don't know can make them feel closer to you.

This doesn't have to occur visually though, I mean, who ever enters your circle of mental awareness circle, such as those who you can't visually see but are within close proximity of yourself can also be close people.

Okay im not quite sure where im going here but I just wanted to point out a few thought that i have conjured up in my little brain, eeeeeenjoy da brain foood.
