Not sure if this is the right place for this, so please move if not so. Okay, I know this probably sounds like a weird question, but I have a setting involving the Undead in an interesting way. Basically, when a person comes back to life, an explosion results from the event that is enough to blow a massive hole in a Graveyard. My question is would it be possible to hide something like that in a world like ours? Or is that quite implausible? The reason I include it is thematic reasons that so far seem important enough to the plot for them. Should perhaps this just be out in the open?
