In the Haunted Mansion at Disney World/Disneyland, "you" commit suicide during the course of the ride and become a ghost.
At the beginning of the ride the ghost host (the narrator) says the only way to escape the mansion is to die, and he shows that he hanged himself. Near the end of the ride there's a moment where the ride vehicle turns around backwards and you go off a balcony, which according to this theory represents you jumping to your death.
Before this part of the ride the ghosts are all trying to scare you, but afterwards they sing excitedly and invite you to party with them. (The Grim Grinnin' Ghosts song.) The only human character in the ride, a groundskeeper, appears after the balcony drop. He faces toward the riders and seems terrified of you.

My Neighbour Totoro was set in a place in Japan where there was a case of murdering of two sisters which happened in the 60s. This event took place on May 1st, while the sister's names are Satsuki (May in Japanese) and Mei (May in English). In the real life case, the younger sister was missing first and the older sister was seen to be looking for her frantically. Next day, the younger sister's body was found in the forest. The older sister was in such a state of shock and kept rambling ambiguous words about seeing a "cat monster", "great big racoon monster" etc to the police.
