Cyberzombies, by V. L. Draven

The horde slowly shuffles forward, minds taken long ago, emptied without understanding. They moan, staring blankly at glowing slabs of metal and glass as they feed on Instagram, Twitter, Facebook. Oblivious, they amble. They are a wave of hijacked flesh taken over by their own volition. Screens wink out. They look at each other: shocked, dumbfounded. They tap their displays hoping for life in empty glass. Faces contort in panic. They scream in frustration and stare at each other in horror. They wail to an uncaring world. Glass comes to life. Their eyes glaze. The horde returns to endless trudging.
