Whenever I wake up to finish something I started doing during dreamtime I can never find the stuff I was working with; it all just disappeared from existence somehow.
Try dreaming about doing laundry or something mundane like that, hehe. Sometimes my dreams are clearly a result of my subconscious brain kicking my conscious brain into gear.
Some of my best or funniest dreams are a result of whatever I was watching on TV when I drifted off to sleep becoming incorporated into my dreams.
