Well, in 'The Hunchback of Notre Dame', the character of Frollo is extremely creepy. His obsession with Esmeralda and his dark, discriminatory views are really unsettling. Also, 'Sleeping Beauty' has its creepy elements. The fact that Maleficent curses a baby to die on her 16th birthday by pricking her finger on a spindle is rather macabre.
One creepy original Disney story is 'Snow White'. The idea of an evil queen who wants to kill Snow White out of jealousy is quite dark. She uses a poisoned apple, which is a very sinister plot device. Another is 'Pinocchio', with the concept of boys turning into donkeys in Pleasure Island, which can be a bit disturbing for kids.
In the original 'Alice in Wonderland' story, there are some creepy aspects. Alice's constant falling down the rabbit hole and encountering strange and sometimes menacing creatures can be a bit off - putting. Also, the Cheshire Cat's disappearing and reappearing act in a rather spooky way adds to the overall creepiness of the original Disney version of the story.
One example could be alternative interpretations of 'Snow White'. Some might say that the idea of a young girl living with seven strange men has some rather odd undertones when looked at from a more modern, critical perspective. But of course, Disney originally presented it as a story of friendship and kindness.
One of the original scary Disney stories is 'Snow White and the Seven Dwarfs'. The evil queen's attempts to kill Snow White, like with the poisoned apple, are quite frightening. Another is 'Pinocchio' where the boys turning into donkeys on Pleasure Island is a really scary concept.
The creepy elements often came from the original fairy tales. Disney was adapting these old tales, and many of them had dark themes from the start. For example, the Grimm's fairy tales had lots of violence and disturbing concepts, and Disney took some of those elements when creating their animated versions.
A story where a young girl adopts a stray cat. As the days pass, she starts to notice strange behavior from the cat. One night, she wakes up to find the cat sitting on her chest, staring at her with glowing eyes and a low growl. Then she realizes the cat has led all the other strays in the neighborhood to surround her bed, and she is trapped. This ending plays on the fear of the unknown and the idea that something seemingly innocent can turn into a threat.
In The Hunchback of Notre Dame, Frollo's obsessive and cruel nature towards Esmeralda is quite dark. He represents religious extremism and lust, which are dark themes. His actions of trying to hunt down Esmeralda because of his 'forbidden' desires are part of the story's darkness.
Well, 'Alice in Wonderland' can have some dark aspects. Alice's journey through a strange and often menacing world where she faces all kinds of odd and sometimes scary creatures. Also, in 'Beauty and the Beast', Beast's initial rage and the idea of a young girl being held captive in a castle, even if it has a happy ending, has a bit of a dark undertone. Then there's 'Peter Pan'. Captain Hook's character and his vendetta against Peter are dark elements, and the idea of the Lost Boys being in Neverland forever without really growing up has a strange and somewhat dark side.
One example could be a story about a haunted doll that moves around at night. It might start with a little girl finding an old doll in an attic. Every night, she hears strange noises coming from the doll's corner, and when she wakes up, the doll is in a different position each time.
A super creepy bedtime story is 'The Dark Woods'. There is a forest near a small village that is said to be haunted. A young girl ventures into the woods one day and gets lost. As night falls, she hears strange howls and sees pairs of yellow eyes in the bushes. She tries to find her way out but it seems like the woods are constantly changing and she can't escape. Every time she thinks she's getting closer to the edge of the forest, she finds herself deeper inside. It's a story that plays on the fear of being lost in an unknown and spooky place.
One example is 'The Little Match Girl' by Hans Christian Andersen. The poor girl is out in the cold on New Year's Eve, facing hunger and the harsh elements. It has a rather melancholy and somewhat creepy undertone as she hallucinates about warm and wonderful things while slowly freezing to death. Another is 'The Tell - Tale Heart' which can be considered in a children's context. The narrator's obsession with the old man's 'evil eye' and his slow descent into madness as he kills the old man and then is haunted by the sound of the still - beating heart is quite creepy.
Well, 'Higurashi no Naku Koro ni' can be considered a creepy animated horror story. It has a rural setting which at first seems peaceful but then turns into a nightmare full of paranoia and brutal murders. The art style and the way the characters' expressions change to show their horror add to the overall creepiness. There's also 'School - Live!', which has a unique take on horror as it starts off like a normal school anime but then reveals a post - apocalyptic and very disturbing scenario.
