Tried to sleep for 4 hours or so without any luck. Unfortunately, the entire time I seemed to be spinning in two almost dreams (like a dream, but you're awake, you know what you're thinking, and you're still aware of your environment, but you're playing a little movie in you head). Neither of them was particularly interesting (read the symbolism was way too deep to give me any insights into what I was trying to work out).

Since I'm up early, think I'll get showered and ready to go and then spend an hour or so on the presentation.
