"A Rose for Emily" by William Faulkner - Why so Creepy?

"What was left of him, rotted beneath what was left of the nightshirt, had become inextricable from the bed in which he lay; and upon him and upon the pillow beside him lay that even coating of the patient and biding dust." This man dies and he is in a bed? What is wrong with this picture? Only, it gets worse! Emily was laying in bed with a corpse! In understand that we promise to love people to their death. But, after death, this type of love is just wrong. How could she even begin to think that such an idea was good for her? Something was clearly wrong with Emily and her mental state. I can just picture the joker saying, "Why so creepy?" to Emily. I cannot imagine anyone performing such an odd task. I don't want to know what else went on.
