I'm very interested in knowing what inspires you to write a poem, take a picture or draw something. I always start getting creative when I'm depressed...or when I'm listening to music. Sometimes I'll just randomly work on a drawing and like the way it turns out...but that happens very rarely...
Haha...it's funny that you'd mention sleep...that reminds me, I always get ideas when I'm extremely tired...but never really get to start working on it 'cause I'm TOO tired to do so XDDD
Music... and depression.. are the times I seem to make the best work. It kinda makes the pencil move like you want it too.
