I find it interesting that you started thinking about him, rather than your own issues. You can't fix him so he's not annoying to you, you can only fix you so you don't find what he does annoying. Likewise, he can't fix you so you're happy with yourself, he can only be happy at the progress you've made.

At first you could not interpret dreams, you hadn't learned how yet. Now you know yourself well enough and through T's example/teaching, you can interpret your own dreams and, since they're your dreams, you know if what he says "rings a bell" or not and adds anything meaningful to the interpretation.

But you are becoming yourself so the voices are separating out; remember this, wondering whose voice you hear -- in a few months or a year or so you won't wonder anymore, you'll know and you'll be wholly you and T will be T and even more wonderful conversations will begin.
