Sometimes we have lucid dreams, that although are lucid dreams, have a low level of lucidity. You may know you're in a dream, but you don't really understand what that means. For example, you may still think all the people and things you see are real. You may have also just forgotten to stabilise the dream and lost lucidity very earl on the dream.
