Your identity and the outer world are in tandem, tugging on each other to shape the perception you hold of yourself. This means that your identity shifts as you steer your focus and concentration on different aspects of the outer world. Compare an American who collects guns and trucks and plays in the NFL to an American who collects books and swords and plays in Swordfish longsword tournaments; now quickly forgetting titular identities, do you think this difference of interest plays a role in their national and cultural identities? Without knowledge of medieval history, you might wonder how France became France and how Spain became Spain. If you know you’re Italian, you might read the works of the stilnovisti and fetch a sense of campanilismo.
Today, ghost stories are shared around campfires and bedsteads as sources of entertainment and have little to do with religion.

Therefore, to reveal how purgatory and other religious beliefs played an important role in forming the attitudes of medieval people, we may want to explore and analyze the common elements in these ghost stories further.
