I'm reading Do Androids Dream of Electric Sheep by Philip K. Dick. The following paragraph is decribing a woman who's just woken up all cranky and doesn't want to get up:
"I just want to sit here on the bed and stare at the floor." Her voice had become sharp with overtones of bleakness as her soul congealed and she ceased to move, as the instinctive, omnipresent film of great weight, of an almost absolute inertia, settled over her.
I'm confused about what "soul congealed" means here. The dictionary says "to congeal" means "to solidify or coagulate". But I don't understand how a person's soul can be solidified or coagulated. Does "soul congealed" mean that she's got low in mood? Can anbody explain the idea for me?
