This time I was having a dream that was not so lucid, and I laid down to go to sleep in it. I began dreaming, but then was lucid! I knew I was dreaming, and that I had control of things. I was even going around to people in my dream and telling them that I am lucid dreaming. I saw various family members and told them this, all the while knowing it is not REALLY them, only a version from my subconscious.
I have never seen myself in mirror why lucid dreaming. I think you are correct you were given a lesson. The lesson i would take a guess to teach you of the dreamer (self) and dreamed (other). The mirror lesson was to show you both. The other was the beat up version of you and this is the other which you have been neglecting.
The only way to ensure the other is kept healthy is to revist the lucid dream.
If you become proficient at that you are then ready for double dreaming. Another dreamer can enter same dream as you and both are fully aware of being in the same dream, can see eachother and interact fully awake.
