To bring demons back from the dead is tricky business, and what you need to do is get some candles, a blanket, and a book of spells. Also, possibly some snacks in case you do bring those demons into the living world, because they're going to be hungry, and you don't want them to eat you, do you? And where you need to go is a graveyard, and you have to go at night. Also, bring a friend, because dying alone is horrible, if it comes to that.
