The authors explore children's symbolic play that involves themes of fear and darkness, and they investigate the nature of children's binary oppositions, particularly between self and other. Their account is based on a year-long qualitative study they conducted with seven children, four to ten years of age. They observed the children engage with play materials, including toys and dolls, at home and on virtual sites such as "Roblox." The play episodes they analyze highlight children's dyadic roles and scenarios and the pleasure of their play involving themes of fear. The authors also address the media and cultural representations that provide roles and narratives for the children to extend this dark play.
