Actually, it was a small girl who left her doom buggy because she was scared and wanted to go into her mom's car behind her, but tripped, and got.. stuck.. under the track.
There are some HM CMs who claim to have seen real ghosts. I know it all sounds silly because it *is* the haunted mansion, but my mom, sister, and I have some sort of inherited phsycic sense(nothing major, just little signals) and certain parts of it feel a little unsettling, and not because of the animatronics.
For some reason, amusement/theme parks are breeding grounds for ghost stories and ghost sitings. For example, at Cedar Point, they say the merry go round in the front of the park will start by itself in the middle of the night, and at the far back section of the park, latenight workers have seen figures walking. OoooOoo freaky stuff!
