How do horror movies scare you?

Needless to say, this is a huge visual impact on the audience.

Movies like Saw and Death Comes can make the audience feel uneasy, fearful and even disgusting just by using bloody and violent scenes.

Or a zombie movie, where zombies' empty eyes and broken legs can continue to walk.

And to be honest, I feel that this kind of terror is the lowest level of terror.

Second, listening.

In fact, to put it bluntly, it is to create a strange and terrible atmosphere through sound effects, especially in ghost films, where some high-energy scenes are often accompanied by screams, thunder or two subwoofers. Drive the audience's inner tension through the sound, or integrate into the plot. Once the sound effects are well matched and the audience is immersed in it, it is time to "scare" the audience.

Third, the plot is reversed.

For example, in a horror suspense drama, the protagonist is chasing a serial murder case with his police friends in the story.

Through a series of events, I wounded the murderer several times and let him escape. Fortunately, the murderer was finally executed on the spot, and Da Zhuo did not change his fate.

The point is ... the last scene of the ending, a wound that should have appeared on the murderer, appeared on the police officer who has been helping the protagonist! The originally kind police officer looked at the back of the protagonist and showed a gloomy smile. (Of course, this is just an example.)

Generally speaking, it is through the setting of the plot and some foreshadowing that the protagonist is in danger.

As people outside the screen, we can't participate in it, and we can only watch the protagonist being added by this danger and breaking out in a cold sweat.
