Happily the next night I was back to good old-fashioned vivid dreams.
There are some interesting mental experiments you can do when lucid dreaming, like the ones where you look at yourself in the mirror. What do you see? What do you see in the mirror when you move? What happens if you move into the mirror? The answers to these questions tend to be very interesting, but also very diverse between people.
Google for Lucid Dreaming and Mirrors, it'll get you to very interesting results.
