Read my lips, no more summer classes

You know that point when you're falling asleep, midway between sleeping and waking?

For the past couple of days, the last thing I remember as I'm falling asleep are word problems being plugged into accounting formulas. I'm not trying to remember them, they just start to play themselves out beneath my eyelids.

Right at the point where I'm thinking sleepily, "Oh I know how to do this! You use this formula, and you start with this part..." I fall asleep.

I've never been able to visualize anything mathmatical so vividly before. It feels like my brain has been permanently altered. Very weird.
