Our Shadow Selves

I wanna write a story but I don't know where to begin. It's like there's all these words in my head and the second I try to get them out they morph and change. They never come out quite the way I imagine.
Our voices are kind of similar. In our head we hear ourselves one way, but to the world we sound completely different. And it's not till we've recorded ourselves in some way that we even notice that. 
Our written word has the same effect on our voices. It's as if we suddenly become a whole new person. As if we're suddenly being introduced with our shadow selves. 
Our shadow selves. That part if us that we aren't quite quite familiar with, The part of us that we bully and ostracize. Embarrassed, we refuse to except it as part of the whole.
Until we begin writing, that is. That's when our shadow selves come out to play. Unknown to us that they're slowly seeping out for us and the world to see.
That's why, I theorize, it feels so foreign to to hear our own writing. Just like it's foreign to hear a recording of our voices. It's as though our Shadow Selves are quite literally coming up to introduce themselves to us. As though they're shaking our hand saying, "Hi, I'm the real you."
