I'll tell you what doesn't make you more creative: depersonalization disorder.
Try writing term papers when your overriding thought is I AM NOT ME
hehe... how does the "i am not me" thought work anyways? I am sure there are people with what your refering to (or maybe you made it up, i have no clue) but if they did have it, what would go through their head? maybe:
"I am not me, i am really an alien that infiltrated this infidel's body. Hopefully i can get out soon."
or
"I am not a me.... I am a tree, why do people keep talking to me, don't they know a tree can't understand them, or talk, or anything else of that nature? Ridiculas. I mean, I AM A TREE PEOPLE!!"
