In most of our dreams, our inner eye of reflection is shut and we sleep within our sleep. The exception takes place when we seem to awake within our dreams, without disturbing or ending the dream state, and learn to recognize that we are dreaming while the dream is still happening.
The consciousness of lucid dreaming is a cultural evolution. It's something that we are talking about and learning about, not biological evolution.
Dream research is a wonderful field. All you do is sleep for a living.
Lucid dreaming has considerable potential for promoting personal growth and self-development, enhancing self-confidence, improving mental and physical health, facilitating creative problem solving and helping you to progress on the path to self-mastery.
It is certainly important to be looking for cures to medical disorders, but it is equally important to conduct research on human health and well-being.
Not all lucid dreams are useful but they all have a sense of wonder about them. If you must sleep through a third of your life, why should you sleep through your dreams, too?
