I just love neurology. Did you ever read "The Man Who Mistook His Wife for a Hat" by Oliver Sacks? It's fascinating. i's problem is that he has such a creative mind that he's compelled to try to imagine such a state. Lotsa creative people do that. I used to work at an animation studio and one day we all opened up and started talking about the darker side of having a good imagination. On one hand, you can come up with some delightful ideas, but on the other hand you can scare the heck outta yourself just riding on an escalator and imagining what would happen if you fell, for example. It's weird. That's why it's handy for creative people to have well-grounded, sensible, realistic spouses and friends whom they can trust to slap 'em back to cold, hard, blessed reality sometimes.
