Shaking the sense of self

Or consider split brains, more chilling than heartening, but posing questions about where will (free or otherwise) materials, and how it can split:

After the right and left brain are separated, each hemisphere will have its own separate perception, concepts, and impulses to act. Having to "brains" in one body can create some interesting dilemmas. There was a case in which, when one split-brian patient would dress himself, sometimes he pulled his pants up with one hand (the side of his brian that wanted to get ressed) and down with the other (the side that did not). He was also reported to have grabbed his wife with his left hand and shook her violently, at which point his right hand came to her aid and gabbed the aggresive left hand (a phenomenon sometimes occurring, known as alien hand syndrome). However, such conflicts are very rare. If a conflict arises, one hemisphere usually overrides the other.

It's possible to shake that sense of unitary self.
