I don't know that for sure - even though Doctors testified under oath that she was not self aware. But, I hope she was not self aware - how would you like to be trapped in a mostly non functioning body for years on end? Imagine being stuck in a (body) coffin, unable to move, unable to read, unable to communicate, etc. - would that not drive almost anyone insane? We would not allow a convicted murder to endure those conditions.
