How are generic elements and camera angles used to create in the attic scene of 'The Exorcist'

The scene starts off with a loud phone ring in the middle of the night and the main character, who is a stereotypical young vulnerable female who is the victim of all the horror, wakes up and finds her daughter sleeping next to her saying she cant sleep because her bed is shaking. The title of the film strongly implies that there is something going to happen. She then hears noises in the attic and goes and investigates. She brings a candle which is a weak light source, making her view of the things around her less clear and more shadowy. The camera films her from behind objects as if something is watching her; she is also filmed from a high angle suggesting vulnerability. The lack of sound creates suspense because it shows that it is silent and she is isolated. The suspense reaches a climax at an unsuspected moment when her candle goes really bright. After that the suspense drops since the man comes with a proper light source and the woman isn't isolated anymore.
