These are some of the most iconic zombies out there though also the most unlikely. We usually see them digging their ways out from their graves and springing up to take the living by surprise. If you’ve ever walked through a graveyard at night you’ve probably thought about these things springing up to get you.
In most cases though coffins are pretty tough things to get out of. Not only are they pretty robust boxes, but they are bolted shut. That alone reveals some of the cultural superstitions surrounding the dead. Plus in many cases, coffins are lowered into concrete vaults.
Digging one’s way out of that would be pretty tough for an able bodied person. For a frail corpse weakened by whatever killed it to slowly tear it’s way out of all that would be even harder.
Despite all that though we could still assume that depending on ground conditions, burial practices and even the weather it might be possible for some zombies to find their way to the surface and start terrorizing the living.
