Dreamed I was drawing a body that kept disagreeing with me

I'm at the drafting table and the cadaver on the page won't hold still — the veins keep rearranging themselves into silver threads, and the surgeon in the corner just keeps saying 'more red, more red' while the whole illustration slowly turns into a thunderstorm. I'm trying to label the deltoid but the letters keep falling off the page like old shoes wearing out. Woke up before I ever found out what the storm was for.
