There are multiple ways that we satisfy our hunger for the supernatural, such as reading books like Twilight or watching TV shows and movies like "The Walking Dead" and "The Exorcist". Our increasing demand for things involving the occult only shows how much we have let it become a part of our daily lives. Even though this may be great news for some, having an obsession over the occult only shows how we have let ourselves fall into the traps that the greedy businessmen have set in order for them to gain more money.
One of the reason for this continuous growth of America's obsession with the occult is tied in with our want of a happy ending. Hollywood showed us through movies, like "World War Z" and "Warm Bodies", that even through all the struggles, there will always be a happy ending. We use these movies as an escape from our real lives and hope that we are able to live the lives of those people on the big screen where everything always ends up the way they wanted to.
We probably would never be able to see vampires or zombies in real life, but it never hurts to hope for it to happen, right? For all we know, the supernatural is probably way more real than the world we are living in now. There could have been a vampire in your science class all along and you most likely would not have known about him.
