Do you ever look in the mirror and the face that looks back at you just seems strange? That the face you see is you? And where are you, really? Within those eyes (even though you know it’s just vitreous humor in your eyes)?
And somehow, people see that face and associate it with you? Except that your face is horizontally flipped from what other people see, so actually they see a different face than the one you see. Just like your voice, which only sounds like you in your head, and everyone else outside of you hears something different.
Then you realize it’s time to go to bed, and in the morning, your face will be familiar again. Hopefully.
