I also have a fear of mirrors and I can't even look in them. Try exposing yourself to it in the daytime, with the light on and someone in.a near by room or ask someone ro stand in the doorway while you try to comquer your fear. As for night mares, use a night light and play calming music such as classical to help you get to sleep. I also have nightmares every night so I watch a little kid show or something else funny and silly on Netflix or hulu before I go to bed. This helps me dream of silly things. :) if you believe in God, pay to him to keep you safe whatever you are, even with your back to a mirror, and to replace your night mares with nice dreams. Also, make sure you are not watching scary movies, shows, videos, reading books, or looking at scary commercials. Even if you watch them in the day time, they will scare you when it turns night time and then you will dream about it.
