The first unintentionally scary film may have been created near the beginning of cinema itself. Some readers might already be familiar with the stories of “L’Arrivée d’un train en gare de La Ciotat”, or “The Arrival of a Train at La Ciotat,” causing 19th-century moviegoers to run out of the cinema in a panic. The film showed a train, arriving at a station, with the camera positioned in such a way that makes it look like it will hit it.
Despite being a great story, this is likely a myth. Firstly, this was a silent film, so it’s hard to believe that moviegoers would think a magically quiet train was fully real as it drove toward them. Similarly, why would an audience of real people suddenly forget that the world was not in black and white? Regardless, it does make for a compelling story about a film that managed to be unintentionally terrifying and only 50 seconds long at the same time.

Modern horror directors use a variety of “tricks” to make our brains believe we are in just as much distress as the characters on screen. The cheapest example is the use of high-frequency sounds played during the film. We don’t actually hear these, but prolonged exposure ends up putting us on edge and can even cause sleepless nights in the long run. So if you want to create a subtly hostile environment for your dinner guests, play something at 20–30 Hz.

Noise has other uses, including loud, contrasting, and clashing sounds that make our brains strive for consonance. Like an interrupted melody, we feel discomfort until the noise or melody is resolved. Directors will then just keep us on edge until the end of a sequence or scene. While this might seem like literally cheap thrills, it’s quite common in the industry nowadays.

Some unsettling techniques are not just used in horror. Psychological discomfort is as present in the crime or drama genres as in any slasher film. Lighting and shadows play tricks on our brains, putting us on edge. Normally, we as the viewer have a better understanding of what is visible than the characters in the scene. But some directors obscure things for the audience as well, making us tense as we try to understand what is happening on screen while the characters do the same.

Despite most people not actually enjoying the adrenaline rush caused by horror films or scary scenes in general, people do have a fascination with unusual circumstances and darker themes. It’s important to note that fascination isn’t the same as enjoying something, as it’s more just our brain thinking that a situation contains valuable information that we need to acquire, even at the cost of sleepless nights, cold sweats, and a rapid heartbeat.
