7. A Real Final Resting Place. People dump ashes in the Haunted Mansion all of the time, Which lends some real credence to those haunting stories. You can read about one such instance here. Ash dumping happens so often that Disneyland had to purchase a special HEPA vacuum that can pick up ashes, but also little tiny bone fragments that are often left behind after a cremation. If you ever hear a Haunted Mansion cast member calling for a “HEPA clean-up,” maybe you want to check out another attraction for a while and come back when the crew has tidied up a little.
I could believe one or two people doing this because it's a little odd, dark, twisted, and frankly kinda funny, but to have it happen often enough that they have a clean-up procedure? Weird. Also, maybe they should post a sign outside "No Ashes Please." Just sayin.
