I like Phantom Manor so much better than the Haunted Mansion...but I forgot how the underworld played in with the bride storyline. Wasn't the phantom trying to convice us to come to his side, or was it supposed to show us what happened after that earthquake struck Thunder Mesa?
In the Bride storyline according to Jason Surrell. The earthquake happened before Melaine married. Henry and Martha Ravenswood died and Melaine disappeared.
But what it shows is what happened to the town and its people in the Phantom twisted view urging you to stay.
I am pretty sure that the falling corpse sound has been added afterwards by whoever mixed the soundtrack, to my knowledge "falling" corpse has not part of the spiel at the DLP, it most certainly is not part of it currently.
Would be great if they could offer both French and English narration...
