The restless sleep potion is an item given to players by Lucille during Song from the Depths. Players must drink it to enter the dream world to find out why the citizens of Rimmington are falling into restless sleep states.
While in the dream world, players cannot interact with any NPCs in Rimmington apart from those in a restless sleep. Dream-state villagers can be seen walking around Rimmington, leading players to the cave where the songs are coming from.
