In "Don't open the door", Donna's dream is highly symbolic and foreshadows that her father is dead. In the later portion of the dream, she's and her father are on opposite sides of a highway, representing that her father has crossed over the threshold of death and is trying to communicate to her not to open the door to her murderer.
In the legend of Oiwa, one can guess Iaman had an easy time convincing everyone his wife's death wasn't murder. If one thinks about it, Oiwa's face becoming deformed from the poison must've been a happy accident, as it allowed Iaman to spin a story about how she threw herself off the cliff out of grief for her lost beauty.
In "Whispers that bite", ever notice Chris and Ryan's "whisper bites" are a yin yang? Chris is covered by bites all the way up to her neck, leaving her face the only untouched part. Ryan mostly has bites and scars on her face. Chris has the luxury of being able to hide her bites as long as she wears clothes to cover them, while Ryan is unscathed except for her face. In a sense, this symbolizes that Chris shall secretly carry her scars as a victim of bullying, while Ryan's history as a bully are figuratively and literally written all over her face.
Also, there's a Stealth Pun to Chris having no bites on her face: even in wake of the Whispers, she was able to save face.
Ever notice that in "The Red Death", we never see Prospero's eyes until the last moment towards the end? Throughout the story, he's either wearing sunglasses or stylized shades. This seems to represent that Prospero was blinded by his pride into thinking his genius and money alone could stave off the Red Death somehow. His losing his glasses and having his bloody eyes exposed also represent his (belated) realization of how ruthless and unbiased the disease is towards the rich.
Fridge Horror:
In "Don't open the Door", one has to wonder, what will become of Donna now that she's been orphaned? And will she spend the rest of her life looking over her shoulder for the man who killed her father?
What's the protagonist in "My Deadly Routine" supposed to tell his wife now that their daughter has roasted to death inside his car?
In "What House are you in?", everything in the Haunted House becomes a million times scarrier in hindsight once it's revealed it's not the haunted house. The television with bloody handprints, the obese man lying on the floor next to a naked mannequin, the screaming and gunshot, they're all real!
