It was October 31st. All of the trick-or-treaters bustled throughout Old Hollow Town, demanding sugary treats. That all ended when they saw the dim outline of a figure next to the woods. It slowly shambled towards the children, lurching and limping. All of the people began to shriek as they realized that the zombie was real.
Unfortunately, one straggler was caught. The zombie bit deep into her flesh, snapping tendons and muscles. She let out one strangled, gurgling gasp then slowly sank to the ground. A few seconds later she rose back up, complexion mottled and green, skin torn and ripped.
All of the stragglers were picked off in that way, and soon, about twelve zombies were lurching through the town. They groaned and clawed at locked doors, knocking a few down. By midnight, thirty zombies were limping out of the town and back into the forest. What had once been a happy procession was now the remains of a grim spectacle.
Red liquid splattered the ground, and the village began rebuilding.
Every year after that, all the zombies would return at that specific time, pick off a few people, and go back to the woods. Visitors stopped coming, and the population dwindled. Soon, everybody died and the town became a horror.
Zombies walked everywhere, hungry for new human flesh. They only had dim flashes of memory from their last life.
What once was Old Hollow Town became known as Dead Hollow Grave.
