Persona 4/Nightmare Fuel

It's a Shin Megami Tensei/Persona game, natch. There's all kinds of mind-shaking imagery in the game, but a few bits stand out.

• The concept that not only is there a serial killer in the neighborhood, but the police have no idea how exactly they're killing their victims. They show up in odd places such as on top of a TV antenna or on a telephone pole, and they have no idea how the serial killer put them up there. It turns out they kill their victims by putting them in the Midnight Channel where shadows will kill them once fog appears in Inaba.
• Shadow Chie, of all people, before transforming. That smile, sweet Christ, that smile. She could give Adachi lessons.
• The calls you get if you fail to rescue someone will probably haunt your dreams. Especially the last one from Naoto, wherein she is murdered by Shadows while on the phone with you.
• Kunino-Sagiri will "save" you!
• Shadow Teddie.
• Shadow Rise, especially the attack animations. She starts humping the pole at one point. With squishing noises. Completely creepy.
• Who the killer turns out to be. It turns out not everyone can be trusted.
• The news that there's a serial killer in the neighborhood is bad enough, but the police have no idea how the killer kills their victims and how they got up on a TV antenna or a telephone pole.
• Though there's nothing stopping the party from making peace with their shadows, they are capable of transforming into frightening creatures when they do not, based on the inner demons of the person whose shadow has appeared in the Midnight Channel. For example, Shadow Chie's shadow transforms into a woman whose being carried by a servant and Shadow Yukiko's shadow transforms into a giant bird who lives in a bird cage.

The Animation

• Episode 1: The silhouette of Yamano Mayumi's body hanging in the pole is chilling. Then we get treated to a close-shot to her face, upside-down, eyes rolled back and without pupils.
