"All good writing is swimming under water
and holding your breath."
Turning blue does seem to secrete a few creative juices.
On the other hand...even if it is true that one must remind oneself to breath while on artistic larks, fascinating details can be had by breathing freely as one float's one's head around in the clouds. I suppose it could be a case of evaporation, where what used to be stream is now atmosphere... and the artistic product is the rain falling to earth.
