Dreamt I was drawing a body with the wrong pen

I'm at my drafting desk and the liver keeps drifting sideways, so I chase it with a blue pen, but the page turns into that heavy green air before a thunderstorm. The surgeon from an old textbook case is in the doorway holding a femur like a pointer, telling me the red isn't red enough. I wake up with my hand cramped and the smell of ozone in my nose.
