Okay, say there was a body stood next to me, without a brain inside it's head.

Let's just say this is possible: If someone were to open my skull, cut my brain in half and put half of it in the other persons empty head, and connect it to the things it needs to be connected too and that half of a brain is still alive.

Where would I be? You know, I as in me that's here right know experiencing reality.

This certainly is mind boggling. I can't see myself being in two bodies at once experiencing what both bodies are seeing and hearing, but then I can't see how I could split into two seperate me's because I'm only one. If I could, what would determine which of the two me's is me, if there is another me, that would suggest there is already another person in my brain that I'm unaware of.
