There is this stereotype of thinking when it comes to dreams that the kind of person you are “psychologically” when you sleep is different from the kind of person you are when you’re awake (invoked in conversations such as whether hearing a voice when falling asleep is the same as hearing a voice vividly enough while awake that someone might be schizophrenic). So then the reasoning often goes that if you look in a mirror, you always see the version of you that you are according to the laws of how the expectations work.
The last time this happened, what did you see?
I’m seldom conscious of my body in dreams, but when it happens it’s often a low-key body horror to which I’m strangely blasé. Last dream with a mirror view, my face had a hideous trypophobia condition that should have been a lot more painful. Oh, that’s happening.
