I am not a hardcore lucid dreamer, but it does occasionally happen, and I am always in complete control when it does.

However, I was kind of thinking...
I was watching a show on the human brain, and I learned some things. When your body needs rest it puts you into a state of unconscienceness so that your brain can 'recharge.' It uses this time basically to let your brain do work as your body rests.

So I was wondering, if you are lucid dreaming, are you still considered unconscience? If you aren't completely unconscience, then does that mean you don't receive the sleep that you need for your body to regain its energy?

SO does anyone know if it is unhealthy at all?

I know some of you will know reasons that contradict me, but it was just a thought that I am curious on.
