NO! NONONO! This is ABSOLUTELY UNTRUE. First of all, Victorians would not have known what a modern zombie is. Zombies as we know them today were invented by George Romero. Vampires wouldn't have been feared because they were largely an Eastern European folktale until Dracula was published in 1897 (the very end of the Victorian era). Victorians would have feared grave robbers most of all. These were used to keep HUMANS from getting IN, not the UNDEAD from getting OUT.
