Which characteristic is common among grave goods associated with vampire burials?

The presence of accessories to prevent reanimation is a common characteristic observed in grave goods associated with vampire burials. These accessories, which may include items like heavy stones placed on the body, iron or other metals, or even certain types of herbs, were included with the deceased to ward off the possibility of the person returning as a vampire. This practice reflects cultural beliefs surrounding death and the fear of the undead, specifically the dangers posed by reanimated corpses to the living.

In contrast, the other options do not align with the customs related to vampire burials. Simple headstones may be more typical of other burial practices rather than specifically for vampires. Magnificent treasures are often associated with elite burials but do not specifically relate to the fears surrounding vampirism. The absence of grave goods is also not characteristic of vampire burials, as the inclusion of protective items signifies a belief in the necessity of guarding against reanimation. Thus, the inclusion of accessories designed to prevent reanimation directly reflects the cultural understanding and rituals associated with the fear of vampires.
