Nightmare Fuel: Sleeping Beauty
The scene where Aurora is hypnotized by the Witches' spell and moves very slowly to the top of the tower where the spinning wheel stands. What makes this scene especially scary is the fact that Aurora seems almost zombie-like and the only light she sees is the hypnotic light ball the Witch made. The rest of the castle is pitch dark. The accompanying music is also eerie. The scariest thing however is that you've always thought that the music in the background was just an "aww" sound in tune. But now if you hear it closely you can actually hear "Aurora" precisely, for added more scariness, after the fire blows out and the room gets dark.
The whole thing even starts with the VERY scary image of Maleficent just staring.
Maleficent: The years roll by... but a hundred years, to a steadfast heart, are but a day. And now, the gates of the dungeon part, and our prince is free to go his way. And off he rides, on his noble steed, a valiant figure straight and tall! To wake his love, with love's first kiss, and prove that true love conquers all! Ahahahaha!
The close up of Maleficent's face when she delivers part of this speech while surrounded by green mist can feel creepy.
Remember Maleficent's death scene? No Body Left Behind. All we see is she got hurt pretty badly, then her shapeshifting, winged self falling.
