I experimented with lucid dreaming a few years ago, and did it for many times. I saw myself in mirrors and also in my own image of I myself sleeping somewhere. My own image was always wrong in some way, and the memories of some of those images are still completely creepy many years after the dreaming happened (I still have goose bumps for the memory of the image of one of these specific dreams... quite crazy really since it wasn't a very bad image that you wouldn't see in a bad horror movie for example).
