Unpleasant Dreams includes two new Character cards called Unwelcome Guests. Deal one or both face up to the table's center at the the start of the game. Guests "follow" the card types noted on them; no matter where it currently is, a living Guest immediately moves to join the family of the character on which one of its "trigger" cards is played. All its Modifiers are moved with it, and it's considered a member of that family until it moves again. This may delay the game's end if a final play draws a Guest to the near-winner's family!
