I slept for at least an hour with a wineglass on my chest while people played Rock Band eight feet from my head. I woke up suddenly either a split second before I spilled the contents of the glass or a split second before my cognitive awareness picked up on spilling. I announced "Uh... I just spilled red wine, but I don't think I got any on your white couch. Oh wait... that was water."
I was having a dream in which I was at a party. The hosts were Brendan and Deleanor (who I don't think know each other) and several other folks who all lived in a house in Boulder. I think there was roleplaying going on and someone had grabbed some Mountain Dews out of the "alphabetic pool." I inferred that one of the rules of the house was that 12-packs of soda were purchased in alphabetic order on a rotating basis, evenly distributed among members of the house. So one person would buy Barq's and Coca-Cola one week, another would buy Dr Pepper and, perhaps, Fanta the next. I don't think it was a 26-item cycle. I also don't think that's an aspect of communal living that requires that much planning detail.
