Insomania Coffin is one of Guertena's paintings located in the Stick Man Room in the Cyan Area of the Dungeon in the game Ib. The painting depicts a coffin with a cross on its cover. Despite the painting having "insomnia" in its name, animated "Z" symbols can be seen drifting out of the picture, indicating that, presumably, the body in the coffin is asleep. Since the "Z"s appear after the Stick Figures in the room have been put back in their Croquis Book, it likely represents the stick figures themselves. In the True Guertena Exhibit, the "Z" symbols are absent.
The painting is on the middle of the wall in the Stick Man Room, which is southwest of the main room in the Cyan Area.
