One knock for your skin, which she will use to patch her own decaying flesh.
Two knocks for your hair, which she will keep between her teeth.
Three knocks for your bones, which she will fashion in to clubs.
Four knocks for your heart, which she will rip out of your chest.
Five knocks for your teeth, which she will polish and keep in a box.
Six knocks for your soul, which she'll swallow whole.
Her eyes were sunken and black like lead,
Her rotting flesh was bruised and red.
And if you ever knew her, she'd kill you dead.
This urban legend is told in Mexico, but you might hear variations of this story through out the world. She also goes by the name La Muerto Blanco. Each knock becomes louder and louder, until you cannot take it anymore. She doesn't want anyone to know about her, and make sure that nobody does...
