I spend most of my time in a room alone where eight hours go by, and I have no sense of time. I work seven days a week, and I live in this sort of vague subconscious fog a lot.
When an accident or a crime happens, there's a period of time before the yellow tape goes up, before the official response becomes formalized. That allows the nightcrawlers to get very close.
When I'm directing, I noticed I'm not using my subconscious at all. I'm literally using the whole front part of my brain all the time. When you walk on the set, every moment you have to be there because something's going on that requires attention.
