It makes sense. Generally, 'creative' people are the folks that stand there and say, "There must be a better way" when a lot of people around them are saying, "But it ain't broke!". Thinking outside the box (or whatever trope you want to use) requires a certain amount of social awkwardness, and often the creative process happens because you can't turn your brain off. Isn't that part of the very definition of schizophrenia? I've seen it in the few truly brilliant - also generally uncomfortable - people I've met. Creativity is driven by being uncomfortable in your own skin, in your own world, in your own paradigm.
I think we've all had moments where we were touched by this sort of thing, especially for the more dedicated writers. How many times have you laid in bed, awake far later than you should be, and finally had to get up out of bed and write down that post, that story, whatever - so that your brain will leave you alone and let you sleep?
