When I finish my thesis I'd really like to investigate some nature-of-consciousness type stuff, because the way the brain works is really interesting to me.
Here's a motivating example from my own brain. I've been in serious thesis-write-up mode for quite some time now. Often, I have problems structuring my writing. A good structure can really improve the readability of a piece of writing, so this is a big problem.
I deal with this big problem the way I deal with all big problems, which is, er, to procrastinate. But after procrastinating, I think about all the stuff I want to express, and start writing bits of it down*.
That (i.e. undirected writing) never works, so then I pace around a bit... okay, to get to the point, what actually happens is that after about 7 hours of this, the way to structure the chapter I'm working on just arrives in my head, apparently ex nihilo, and it all makes sense, and that ends up being the structure I use.
It seems like my consciousness isn't very involved in the creative process at all, but is instead content to just sit back and have fun. Kind of like the tourist sitting in a boat watching Disney's "It's a small world after all", who doesn't know about -- or care about -- the phenomenal amount of work that went into building the attraction**. So, to whatever part of my brain is doing the actual work -- hi, could you possibly hurry the fuck up? I'm keen to move on.
*There is a theory that doing a bit of work and then procrastinating for a while is more productive than trying to maintain focus for hours and hours. For obvious reasons, I find this theory to be very seductive.
