Dreams
I don't remember how it began, but I do remember standing outside a convenience store with friends, reading an illustrated fake book (much like a mother goose book with music written for each rhyme) by streetlight. Someone "not-my-friends" showed up and started being an ass, ducking under my arm to read the book as I was reading it.
So I elbowed him in the eye.
He got pissed off (naturally), and walked into the convenience store to get his own book/magazine. When he emerged, he shook everyone else's hands in an exaggerated manner. I took off my glasses resigned to my fate: when he walked up to me, he punched me in my right eye.
I ended up riding/driving a vespa-type scooter with someone else out of a nearby parking lot, having stuffed a drainpipe full of plastic bags. At some point between these two locations, I looked up at the night sky, and found it very difficult to open my right eye, thus telling me I had a black eye.
Once I awoke, I realized I was buried facefirst in the bed, with my left side up. So if I were to open my eyes, it would be much more difficult to open my right one.
