For our trailer we decided not to include any dialogue as with the storyline we thought it would be better for their not to have any dialogue in order to add more tension and suspense. Due to the fact that her nightmare consists of someone watching her therefore there is no dialogue exchange between the two characters apart from the protagonsit screaming. In some horror trailers a voice over is used which we decided we would include at furst however after considering this we decided that with our storyline a voice over may not have worked and therefore decided to go with using just non-diejetic sound.
