I do not see this kind of graves on movies like Interview with the Vampire, Zombieland, Walking Dead, True Blood, Dracula, Twilight series or any other movies about zombies or vampires. The image above is a grave from the Victorian age when fear of zombies and vampires was prevalent. They put cages in the tombs to the intension of trapping the undead just in case the corpse reanimated. Or have they also incorporated this on zombies and vampire related novels.

Well just ranting, or maybe I just wanted to see on movies the resurrection of the  dead bodies and how they cannot get out because of the cage. (hahahah)  but I remember one in True Blood when they trap vampires in standing tombs alive but with concrete only and there is no cage. (hahaha).

Thanks for 9gag.com for the image.
