From every ghost story recounted by a cast member or a guest, the ghost always appears to be a little boy. Perhaps it’s the same boy whose ashes were spread throughout the ride.
This particular picture has been making its way through the Disney parks haunting rumor mill. The photographer claims there were no children in the ghost's supposed age range in line near him to get on the attraction. There was also no flash or visible light coming from the camera to make the boy's face glow.
Another Haunted Mansion story includes a cast member loading one of the stretch rooms by herself at night when she heard a child laughing. She assumed it was the next batch of guests coming to ride, but no one arrived. She saw something move at the corner of her eye multiple times, but there was nothing. She started to feel cold and felt someone put a hand on her shoulder . . . but no one was there! She ran out of the attraction screaming and requested to never work the Haunted Mansion.
There have also been multiple sightings from guests and cast members of a child playing in the ballroom scene and a child who appears to be crying at the exit and disappears.
Either the Haunted Mansion is really haunted or Disney’s just getting really, really good at its visual effects!
