I had a very vivid dream this morning just before my alarm clock went off. It was an Indiana-Jones-meets-video-games puzzle, a carnival booth in a dank cave in which I had to open a chest in order to receive my prize, or move onto the next level, or not die (dreams are sometimes weirdly non-specific about motivations). There were pressure plates, and supplies for small explosives, and pulleys and levers, and buckles and snaps, and lots of sand. And an egg, but I don't think that's relevant. I had to use contextual clues to figure out how to open the chest, plus a healthy dose of trial-and-error. What happens if I connect this buckle to this pulley, then to this pressure plate? Nothing explodes? Okay. What if I connect all six pressure plates to the same weight? The chest moves closer? Great.
Of course I woke up before the dream ended, but I'm still intrigued. Puzzles! Logic! Mental tests! Tips from the context! Trial and error!
Oh. I must be translating literature again.
