I had a very strange dream. I was gathering lint.
I was on my hands and knees, on a carpeted floor (itself rather alien, given how rare carpeted floors are, here in Korea), picking up little bits of lint. Once I'd gathered a small handful, I'd stuff it into a plastic "Family Mart" (convenience store chain, here) bag. Then I'd get down and get more lint.
I wasn't the only one doing this, in the dream. I had students and friends helping me. There was a lot of lint to be gathered.
That was the whole dream. It was stunningly vivid. And utterly pointless.
OK. What the hell does a dream like that mean?
