meaning of card facing away from you: recovery, rejuvenation, inevitable end
The dementors are very interesting creatures. They stand guard for the wizarding prison, Azkaban. They feed on every happy emotion and, if given the chance, the human soul, sucked out through what is called the "Dementor's Kiss". Dementors have betrayed Harry in many ways. They kept his uncle captive for thirteen years even though he was innocent. The dememntors don't really care about innocence or guilty, but they were guarding him in the prison that he was placed in under false pretenses. In the fifth book, two dememntors ambush Harry and his cousin, Dudley in their neighborhood. As creatures who are supposed to stop bad people form getting out of jail, attacking innocent teenagers is very far from what they are supposed to be doing. Finally, during the war, they deceive the entirety of the wizarding world by siding with Voldemort. They torment the wizarding world and the rest of Britain. They obviously did not just betray Harry, but the wizarding world as well. They felt betrayed when they allowed Sirius to escape and when they flipped their loyalties to the other side.
Though dementors do not kill people, they take everything away from them. When a person receives a dementor's kiss, they lose their soul. They become just a body, wandering aimlessly through the world without care or purpose. They lose everything and their life comes to an end, even if they are not dead. This can be a good thing in some cases- it makes sure that a bad person will stop doing harm. But it is also bad especially because it is the way dementos get food, so they don't really care whose soul they take. They almost ended Harry and Sirius' lives in the third book.
The only way dementors can represent recovery and rejuvenation is through the spell that pushes them away- the Patronus. The patronus is a spell that creates a guard of whoever is casting it. It takes form of an animal that is personal to the person casting it. Harry's is a stag (the animagus of his father). Hermione's is an otter and Ron's is a Jack Russell Terrier (an animal known for chasing otters). Snape's was a doe which was the same as Lily's. These guardians are basically made up of light I think, which is something repels dementors (creatures who prefer the night). The spell is a beautiful one, to say and to look at.
