If one subscribes to the belief that specters return approximating their most recent living form, each of the ghosts died after shaving her pubic area.
The dead spend most of their time slowly bobbing up and down in the pool and rubbing themselves, but occasionally one wanders into the house, as we see above, and manipulates a strap-on attachment into the terrestrial parts of the real estate agent.
I was unconvinced, but I'm sure GhostMILFs isn't too far away.
