Nightmare Fuel: Black Swan
Black Swan is considered a "live-action version of Perfect Blue". With the parallels and existence of the latter's NF page, those words are truer than you might believe.
The entire "Night of Terror" sequence, as it's called on the score, which is basically 10 minutes of Nina going completely MENTAL the night before her performance, as we are treated to Body Horror, Hell Is That Noise, and jump scares, just to name a few things. Unsurprisingly, that is director Darren Aronofsky's favorite part of the movie.
The major turning point is Beth (Winona Ryder) stabbing herself in the face with a nail file whilst screaming "I'm nothing! Nothing!" And then her face turns into Nina's, who runs for her life as Swan Lake music BLARES over the soundtrack. And when she gets to the elevator, she discovers she is holding the nail file. All of the other hallucinations reveal themselves to be hoaxes shortly afterwards, but this one is so extreme, it fully confirms that we have reached the point where we can't trust ANYTHING about the movie. And consider that it may have actually been Nina who stabbed Beth.
When Nina gets home, someone whispers "sweet girl" from the darkness of the kitchen and there's a bloody figure standing in her kitchen when she turns the light on. And then the paintings start screaming at her.
Nina's final Black Swan wardrobe and makeup is more than a little frightening.
Her first appearance as the Black Swan, including with Nina's initial lunge to the camera, with that disturbing growl.
Then there's the moment when, after noticing the blood on her fingers, she starts cutting her nails whilst looking in the mirror with a psychotic expression on her face, while disturbing laughter can be heard...
The part where Nina slammed the door with her mother's hand still on the doorframe. Her mother's screaming in pain only makes the scene even worse.
And then shortly afterwards when she twists her mother's injured hands. Did this movie have a thing against hands or what?
The climax (pun not intended) of the sex scene. Lily stands up and whispers "Sweet girl" before suddenly transforming into Nina's doppelgänger and attempting to smother Nina with a pillow. The way sweet girl is said.
The things that are obviously unreal are disturbing, of course...but the things that might be real are even more unsettling because by then you realize you can't trust anything about the movie.
Nina peeling off the skin of her finger in the bathroom.
Her "goosebumps" that turn out to be more literal than thought at first
And then later her neck freakishly elongating like a swan's.
As a reclusive perfectionist, in more then a few departments, the pure fact of Nina's whole experience in the movie coming from her desire to be perfect...I just want to be perfect indeed.
