When she gets up, and the blowdryer turns of, it gives us an idea that someone is close enough to kill her. The hairdryer then gives her an electric shocks, by that, it is getting tense and makes the audience feel more worried and excited. The camera slowly moving around to the mirror, facing it to see her face suggest that someone is right next to her and about to pop up. Tension is created in many ways, by now the audience will think her life is about to end. A lot of digetic sound have been used such as the hairdryer and the water. There were also many different types of shots used in the film such as extreme close-up which was showing her eyes, medium shot which showed her drying her hair and also paning, which was slowly zooming in the bathroom towards her.
Overall i think this film had a lot of tension coming up and it gave the audience shock espically because of the camera angles and the non-digetic sounds at the begining.
