when we see we can understand what we are looking at, we can also visualize what it is that we have seen if we commit it to memory. But why do we visualize our thoughts only to the front of us? for example visualize a train moving through your mind, do you see it right in front of you? well i have found difficulty seeing images or thoughts anywhere but where my eyes can see. Any point beyond my perefrial vision i cant visualize on. This leads me to beleave that we think in 2 dimentions. Is it possible to visualize in 3dimentions? and what would our thoughts be like without sight? These are just some of my thoughts of conscienceness.
