Do you know the baalspawn monster form from BG2? Something like that.
That was a joke.. I have incredibly detailed dreams, meaning that there are quite a few I remember vividly years later, but no, cannot actually recall looking into a mirror in any of them. (though in steamy dreams the parts of my body in my field of view were similar to real life)
There is a movie I supposedly saw as a 9-10 year old child, but I'm no longer sure it was not a dream. I remember it in vivid detail, but there were only so many dinosaur movies made in the 70-80s & it does not seem to be one of them. Described the plot & prominent scenes in the past on movie subreddits & also to LLMs & there is no hit..
