When you undergo anesthesia, you can really feel what I would assume is my sense of self slipping away. And if you're someone who is sort of babysitting a person who's getting an operation, you can actually watch as they wake up. Their sense of self return to them. Well, you can see it with just mourning. It's kind of weird that you kind of lose your consciousness every night and somehow the brain reconstructs that character in the morning. But yeah, generally your brain can reconstruct that character, but that's a constant process of reconstruction. As we get older, of course, you see the progressive loss of that characterization in dementia.
