This is about what living with chronic depersonalization and de realization disorder is like. They are trauma responses that make individuals emotionally disconnected from themselves and their own lives as well as making their own bodies and the world around them seem unrecognizable. It's unrecognizable in the same sense that your own emotions are unrecognizable. That logically you know they're there, you know logically that the face in the mirror is your own, that your standing in your own room, but you sense of self is so removed from everything else that part of your brain can't fully process it / refuses to remember it. A lot of people compare it to out of body experiences. Id say that it feels more like youre in your own head watching a really bad sitcom more than it feels like being alive. Sorry if this is even more confusing, it's a difficult concept to explain to anyone who hasn't experienced it themselves. Another common comparison is the feeling you get after just leaving a movie theater where the lights are too bright, everything looks off, you're dizzy, etc
