Great dream, congrats on lucid #20 and the flight milestone! Several things you did in that dream are extra noteworthy in my opinion. Instead of just saying "Waaah, I want a mirrorrrr," you thought of the details you wanted and it appeared! Then when your reflection wasn't cooperating, you decided to do something else, which ended up being you accomplishing a personal goal. This is much like real life isn't it? Say fuck it to the thing that isn't working in the moment you want it, and put your efforts somewhere else, and you meet with success that way.
