My head is its own narrative.
It's strange, really.
I do something, and my mind immediately races to narrating the next move; what someone else may be thinking; what will happen later as a result of my action. It's like a book. Think about it. A novel written in 3rd person constantly switches between the past present and future- the internal thoughts of characters, the proceeding actions of characters. 
I see a mosquito, and I'm about to kill it, and I clap my hands together and my mind starts thinking about, in a narrator's voice, how the death of this bug will affect the whole population of bugs, and some other fantasy that my imagination forsees. 
I wonder if I'm actually looking into the future.
