An anecdote from sleepiness.
This one time, some friends and I went camping, without any equipment. We shared a bottle of vodka to keep warm, and then the other two started to make out. At the first crack of light, i was out of there. I didn't tell them that I left, or why I did. While I was waiting for the bus to take me back, I saw a hummingbird the size of a bumblebee. It disappeared in a second or so. It was magical.I was miserable; my back hurt from sleeping on rocks, I was cold, and tired as fuck.
