I think I've been a bit ahead of the curve with lucid dreaming while awake. I can think as far back as having been doing that since I was 13.
After I taught myself how to sleep with my eyes open (out of boredom, and having heard of it at the time, or seen it in a movie), I just figured if I can dream with my eyes open, what would happen if I were to "wake up"; but my eyes are already/still open? Definitely made some days more interesting. Learning how to have, and maintain, a mid-wake state in order to more easily induce it into action was another challenge. Of course, growing up, I realize I just had to freaking meditate.
EDIT:
Now that I think about it, I think I remember where I left some of my more artistic ideas (mentally). Provided enough time, I have some art projects to do.
EDIT EDIT:
Last fey mood I had recently, accidentally triggering it again, led me to make this Halloween art project:
It's a Jack-o-Lantern House.
And another thing: If you can also retain your senses when you dream (accidentally stumbled upon this since the first time doing that mid-wake dreaming; must've tricked my mind (or spirit) into perceiving another reality by accident), you're able to not only see and hear in your dreams, but the rest of your senses work too (smell, taste, touch, and any extra-sensory stuff as well, I suppose). Now, combine that with lucid-dreaming while awake. Feel free to re-engineer reality.
EDIT EDIT EDIT:
Now I can't help but to want to experiment with ideas regarding the movie Inception doing this. Being full-sensory mid-wake dreaming, while attempting inception. The crap you can pull...
