Subconscious writing

This is an attempt at writing down my thoughts as they come to me. The idea of subconscious writing alludes me. These words, where are they coming from? When have I heard them, or thought of them? Is it possible that just the act of writing brings them into existence? Which brings me to the question, why do we do the things we do? Where do thoughts and ideas come from? How am I and what makes me; me?
