You are Michael Green. I am your subconscious.
You happen to wake up in a room, and someone or something is assigning your personality. You are sent to Equestria. From there, you will decide what you will do. But be careful, because anything you do will determine if ponies like/dislike you, or could worsen or lessen the conflict.

(Quick side note: it will start off for everyone, but if your decisions are darker and more suited for teens. It will be changed)
