Lost Souls appear in a room, seen in the hall where the Janitor is cleaning by Adam Maitland and Barbara Maitland.
Trivia[]
Had the exorcism of the Maitlands succeeded, this would have been their fate. In fact, the process was already happening during the exorcism scene, as Adam and Barbara could be seen slowly taking on the appearance of the Lost Souls they saw earlier, with wrinkled, dry, decaying skin and patchy hair with drawn-in noses and sunken eyes, and very brittle to the touch. Before Betelgeuse saved them, they were likely moments away from being transported to the Lost Souls Room.
During exorcism in this universe, it would seem the spirit begins to decay as though it were a corporeal human body. This is because during this ritual, the ghost is brought back to the world of the living to be once again destroyed, leaving the scars and wounds imprinted to the body of the spirit, giving the lost souls their almost stock ghost appearance, complete with tattered, sheet-like clothes and a grotesque, zombie-like physique.
When Otho tried to exorcise Barbara and Adam, he had no idea he would have to in the process torture and kill them, believing it would simply banish the spirit from the home after being revealed. He also didn't know it couldn't be stopped by the exorcist, and ultimately had no choice but to accept Betelgeuse's help.
