Frightening fiction provides a safe way to learn how to deal with fear and anxiety.
Anything that is feared, can be tackled with knowledge. Fear during a global crisis generally arises due to lack of knowledge on how to deal with the situation. Helplessness and uncertainty give rise to the feelings of doom and gloom. The way to tackle this is to be completely informed about the situation, and be ‘apocalypse ready’.
Why do we love to watch scary horror films? Some psychologists claim people go to horror films because they want to be frightened or they wouldn't do it twice. You choose your entertainment because you want it to affect you. But what else does the literature tell us about the psychology of horror movies?
Look past the tatters and putrefaction. Scan the bent and broken bodies shuffling toward you. Do you recognize a coworker, a neighbor, maybe even a loved one? It's the zombie apocalypse - and it's an idea that ever more academics are taking seriously.
A lot of symbolism can be interpreted in popular zombie films.
The undead are the ultimate other of any us-and-them division, especially if you consider us to be savvy and them to be brainless. But Zombies were not used as just a frightening enemy, but were used to show the ills of the society: consumerism, capitalism, terrorism, etc.
