Two words for 'I'? Listener question

It looks to me like we are using the same word “I” for 2 different experiences;

There seems to be the Big I who is not identified in as the doer/controller and takes into account both the conscious and sub-conscious mind and then there is the little i  that is totally identified in as the separate self. Am I seeing this correctly?

If so, would it not be so much easier to use different words for the entire “I” (I) and the smaller conscious part of “I” (i)? It seems that every time I use the word “!” To describe my identified self (i) I re-enforce the misconception about who I really am.

When I try to imagine how this would work in practice, I think it will be helpful for me to simply ask myself when I use the word (I?i) which one I mean.
