In When I Dream each player takes a turn being a "dreamer," trying to guess cards as the entire table gives them one word clues. But there's a catch: some players are "fairies," trying to help them guess correctly, and other players are "boogeymen," trying to cause them guess incorrectly. (There's even a sandman, who simply strives to keep balance). At the end of their two minute turn, the dreamer attempts to recount as many correct guesses as they can. The game is scored, and the next dreamer takes their place.
