"Dreamcatcher" is a quest mod for Fallout 4, where players are tasked with investigating a strange occurrence tied to dreams and the supernatural. In this quest, the Sole Survivor encounters an agent from Bureau of Unnatural Investigation (BUI), who informs Survivor that a wealthy individual has fallen into an endless nightmare, and it’s up to the player to investigate the cause by entering his dream.

As the player progresses through the dream and real worlds, they must navigate surreal landscapes and uncover hidden secrets.
