Actually, I feel just the same. I was going to post this but now there isnt any need. I know excactly what you mean about the mirrors (I have experienced looking into a mirror in a dream, its not nice) But I dont think you will be forced to look into a mirror especially not if you go lucid. Although I havent had one yet I think lucid dreams could help you overcome this fear.
I am also keen to try WILD but I cant bring myself to do it becasue Ive heard about halloucinations and what-not. I do hope you find an answer to your questions.
