1. Angel Lore
1.1. Created by God after the leviathans, were the angels and the four archangels: Michael, Lucifer, Raphael and Gabriel.
1.1.1. God created humanity some time after the angels, and placed a high value on them. Lucifer refused to accept the position in the divine order apportioned to humanity, and defied God's word. After Michael cast him from Heaven, Lucifer twisted a human being to create the first demon, Lilith. For his crimes, Lucifer was imprisoned in a cage locked with the 66 seals. This conflict had lasting repercussions, including Gabriel's descent to Earth. At some point, God also departed Heaven, leaving the angels in charge.

"Red Riding Hood" – In the version by Charles Perrault (1697), Red Riding Hood is not rescued but is eaten by the Wolf.

3.2. Bloody Mary
3.2.1. An urban legend that says that anyone who chants the words Bloody Mary three times in front of a mirror will summon a vengeful spirit. This spirit has been reported to do a variety of things to the person who summons her, including killing the person, scratching their eyes out, driving them mad or pulling them into the mirror with the spirit – generally referred to as the spirit of a woman or even a witch. This is an old legend, but in 1978 a folklorist named Janet Langlois published an essay on Bloody Mary, which led to the tale becoming a popular slumber party ritual done by girls as well as boys. No one knows the origins of the Bloody Mary legend; over the years, she has been rumored to be anything from a witch that was killed for practicing witchcraft to a modern-day woman killed in a car crash, depending on what part of the country you live in.

The princess loved the nobleman deeply and had two children by him, but Montesclaros refused to marry her. When he finally deserted her and married another woman, Dona Luisa went mad with rage and stabbed her two children. Authorities found her wandering the street, sobbing, her clothes covered in blood. She was charged with infanticide and sent to the gallows. Ever since, it is said, the ghost of La Llorona walks the country at night in her bloody dress, crying out for her murdered children. If she finds any child, she's likely to carry it away with her to the nether regions, where her own spirit dwells.
4. Creatures and Spirits
4.1. Leviathan
4.1.1. The Leviathans, also called "The Old Ones", Chompers, or Levis for short, were ancient, primordial monsters, as well as God's very first beasts. Thus, they pre-date angels, humans, and the soul itself. The creatures proved to be too hungry and destructive, so God created Purgatory and locked them inside. They were inadvertently released when Castiel opened Purgatory and absorbed all the souls inside in order to defeat Raphael.
4.2. Reapers
4.2.1. Reapers are angels that serve Death. They assist in maintaining the Natural Order and used to be thought as completely neutral, aligned with neither Heaven nor Hell nor Purgatory. According to Castiel, Reapers will sometimes appear in mass gatherings in prelude to a great disaster such as the eruption of Mount Vesuvius in Pompeii.
4.3. Vampires
4.3.1. Vampires, or Vamps for short, are a race of blood-drinking supernatural creatures that were once human. They have been encountered by the Winchesters, Gordon Walker and other hunters. However it has been stated encountering a vampire is very rare as hunters have hunted them near to extinction although due to their ability to reproduce by transfusion there only needs to be one for them to repopulate.
4.4. Ghosts
4.4.1. Ghosts, also called Spirits, are souls of deceased humans that did not go with their reaper to Heaven or Hell and are stuck on Earth. The word Ghost is a common term for a soul that did not move on to an after life after they perished. They typically reside in The Veil, but they can occasionally appear in the physical plane. Descriptions of the apparition of ghosts vary widely: the mode of manifestation can range from an invisible presence to translucent or wispy shapes, to realistic, life-like visions.
