The genre of horror is an extremely wide genre, that gives a certain freedom of creation, allowing reality and fiction to merge. This is why while watching some videos treating about horror movies and its elements (see post "Youtube videos" https://needsomeblue.wixsite.com/mysite-1/post/videos), I took notes so I could have creative inspiration regarding the narration of the short film. The taken notes regarding the different topics are the following :
Fear: Treats about phobias, discomfort, representation, and simulation.
Sound: High pitched, fast, repetitive, mechanical and crescendo sounds or kinds of music plays a lot.
Cliches that can be used: Dramatic irony (when the character or the viewer knows a crucial piece of information but the other does not) ---> the spectator sees the menace but the character does not.
Alcohol and drugs ---> Weakens the user to the exterior factors and becomes a threat to itself and the others.
Jumpscares: are short, fast and at the last moment.
A good example of unusual and effective jumpscare is the hospital one in The Exorcist III: Long shot, no sound, no movement, sudden.
