Hypothetical Situation.

[General Mostly Electrified Steel]

Let's assume you are you.

For the most part, this means that your personality is a specific and finite subset of your mind, which can be taken to be personality + unconscious.

However, this becomes important for the next bit.

You are everyone else.

Now, the question:

Who are you? There are no rules, and the framework is simply that: a framework. You can paint it, stretch membranes over it, play jungle gym with it, snap pieces off and beat people to death with it... the choice is yours.

But...

Who are you?

I am large, I contain multitudes.

It's a question without an answer. If the question is what I would be if my consciousness were to suddenly be in control of everyone else's the answer would be that I am me. Nothing changes, except that I would eventually go quite batty. That answer, though, is based on my view that we are self-defined. If one views things in the opposite way, and instead argues that we are defined by interaction, the loss of all other consciousness would be a loss of self. Of course, if you're a solipsist, the world is entirely within your brain anyway, so everything is a creation of your imagination

I quite agree, I must say that i am me, for that is all i know that exists, "i think therefore i am" etc. As for what I am i must be a thinking thing. But as per a physical existence I cannot say. Does physicality even exist, it cannot be proven, thus I can imagine myself as anything I wish although I cannot ever prove that that extended part of myself exists. As for others, are there even "others"? perhaps there is only me, as i cannot prove that any "other" exists. It can be said however that all these things i have an idea of exist as ideas, as modes of my thought. But now i'm getting off topic.
To get to the point, my only logical reply to this question is, "I am me, and I am a thinking thing."
