You died and came back. This experience changed you and defines who you are today. The specifics of your death are up to you, but the following questions and suggestions will help you determine your odd personal history.

How did you die? It probably wasn't of old age. Spells like raise dead can bring back those who die before old age takes them, but after dying of old age there is almost no magic which can bring a person back to life. Was it combat? An accident? A disease?

How long were you dead? Spells like true resurrection allow a character to return from death after as many as 200 years. How has the world changed politically, technologically, and culturally since your death? What remains of your family, friends, and personal life?

What was your life after death like? Did you spend time in the glory of eternal battle is Ysgard? Did you enjoy the paradise of Elysium? Were you tortured in the Nine Hells or Abyss? Do you remember nothing from that time?

Maybe you didn't completely pass on, but lived life as an undead, such as a ghost or vampire. Why did you become such a being? What acts did you commit that you now regret? Who still thinks of you as a monster?

Finally someone brought you back. Who was it, and why? Maybe it was to face an old enemy. Maybe it was a loved one who searched for a long time and sacrificed much to revive you. Maybe you were brought back for a secret only you knew. How did this person bring you back? Was it straightforward magic? What about a spell like reincarnate, which could bring your spirit back in the body of a different humanoid race? Or maybe it was some other magic that has a more sinister secret.
