Lol I think we all think, "Is THAT what I sound like? OMG." They say that even if you saw your identical self walking past you, you probably wouldn't agree that it's your twin. We have such a different perception of what we see in the mirror (or hear with our own ears) compared to what reality is. Probably more true for the visual perception versus audible one since there are other factors that affect sound.
Anyway, I digress...Love having deep conversations about these things! They're very "real" and mostly kept on the DL because of that fact.
