Anon,
It will be Sunday before I will be able to fully analyze your dream. A quick glance {cursory} I see these possibilities.
As is the case with all dreams there is evidence of conflicting emotions. It may have to do with some required event in your life where something occured that left you feeling unprepared with failure being what frightened you {in actual waking life}. Afterwards you realize it wasn't as dire as you thought because you are in control of important aspects of your life that matter most {related to creativity being a good possibility}.
As for the lucid dreaming. Unless you were aware or suspected early in the dream you were lucid dreaming this does not seem to be a lucid dream, a normal one at least. With lucid dreaming you are able to control aspects of the dream. The last part of the dream where you remembered you were dreaming may be more about the control of your life I mentioned. The desire to be anywhere else besides being right there may be addressing not only a desire to be where you want to be most {creative?} as well as a desire to be elsewhere related t an actual event in your life. Dreams do that with all dreams having at least two applications/meanings. This page will explain lucid dreaming Lucid dreaming: Controlling the stories of sleep.
What numbers are you speaking about? I have the belief all numbers have meaning but not all important. I see numbers related to time of day and length of time and although they may have relevance they alone aren't suspiciously pointing to clues to the dream. Are there other numbers you didn't include in the dream post?
