Zombies and their meanings

A huge part of sci fi and horror is based on the concept of zombies. These mysterious and mindless corpses instill fear and panic in people's minds. It is interesting to analyze how these creatures came to be. The idea can stem from the AIDS virus. When AIDS was first introduced many people that were infected were stigmatized and mistreated. This draws parallels to how zombies infect humans and how they are viewed as diseases. Another idea can be see in factory workers of modern age where they are just cogs in a machine, mindlessly focusing on one aspect of work such as installing a screw. Zombies operate in the same way in that they only focus on feasting on flesh mindlessly.
