Sweet dreams is a "one-sheet" horror RPG in which players take the roles of participants in a sleep study in the mid 1970s. The front page details the scenario setup, character creation, and system rules, while the back page covers GM-only scenario information. All you need to play is this PDF, a standard deck of playing cards (or more than one deck, if you like), and some paper and pencils (or any way of tracking/recording minimal game info).
