That night, Lisa reads the book and talks to Gravedigger Billy, Groundskeeper Willie's cousin, who works in the cemetery.
Homer and Lisa stay awake watching television, preventing Marge from sleeping, so the parents see a therapist.
When she hears the police stepping on a twig, she runs in fear and faints after hitting her head on a tombstone.
"[5] On Four Finger Discount, Brendan Dando and Guy Davis liked the episode, highlighting the animation and music during Lisa's nightmare.
Lisa experiences that consequence when her phobia of the graveyard intensifies and expands the more she seeks refuge in her parents’ bedroom.
