$0 As the music builds into a blood curdling tune and foggy shadow appears onto the screen, you can’t seem to think happy thoughts. Eyes tightly shut, fearful of what gruesome scene you might get a glimpse of, forehead dripping beads of sweat, and now forced to restrain the full fledged squeal that is rising in your throat; your thoughts are very much the absence of happy. The single hope that is keeping your skin attached is the fact that the horrifying creatures on the screen have no chance of following you out of the theater. $0$0 Yes, when the credits roll, you’re safe. Of course, you are far too old and experienced to consider that these monsters exist outside of the movie screen. The monsters that terrorized the innocent townspeople and limped away from empty graves are obviously fictional. Or are they? $0$0   Society has long accepted the idea that vampires, werewolves, and zombies could never be real. A mother would comfort terrified children with “there’s no such thing as monsters” in the same breath as she might offer a band-aid for a paper cut; it’s a common belief. People have turned down any thought or comment concerning the validity of monsters, perhaps to muzzle the fear that would ensue. $0$0  Any truth associated with monsters has always been considered strictly myth or a fabrication. However, there may be a real scientific explanation for sightings and real life accounts of the creatures of the night. Scientific evidence has uncovered that the famous monsters movie goers have seen in their nightmares, can be explained by… science. $0$0  While watching Dracula, Spanish neurologist Juan Gomez-Alonso noticed that vampires behave similar to people with rabies. The virus attacks the central nervous system, altering the moods and behaviors of those infected. Sufferers become agitated and demented, and their moods can turn violent. Rabies also causes insomnia, which explains vampires being nocturnal. Also, rabies can create a person to suffer from muscular spasms that can lead them to spit up blood, which is triggered by bright lights, water, or strong smells, such as garlic perhaps. Do you need a quick review of an everyday vampire or is this sounding pretty familiar? $0$0  In The Werewolf Delusion (1979), Ian Woodward explains that werewolves may also be inspired by rabies. The virus is transmitted through biting, and the dementia and aggression of late stage rabies can make people behave like wild animals. $0$0  According to Costas J. Efthimou, a physicist at the University of Central Florida, zombies may also be creatures of science. This is supported by the story of Wilfred Docient’s death in Haiti and reappearance in his village more than a year later, looking and behaving like a zombie. Wilfred was poisoned with a powder from the liver of a species of puffer fish home to the waters of Haiti. The powder caused Wifred to appear dead, without actually killing him. When he reappeared, he was brain-damaged, and wandered the countryside for months until ending up at his village. This doesn’t exactly sound like Night of the living Dead; however the same basic principles are there. $0$0  No, this is not a mockup screenplay of the next horror movie; it is simply the latest scientific conclusions that may legitimize a few fears. While these diseases and the particular symptoms are rare, so are the chances of seeing a vampire walking down the street. A number of popular monster movies could actually be based on real people plagued by diseases. Maybe these movies just left out the part where the incredibly crazed monster is diagnosed with a rare illness.$0
