My initial group idea

My Initial Idea-

It opens with a blank screen, where a hearbeat then comes in and gets faster, and then a teenage blonde girl jolts up out of bed from a nightmare, with a close up of her face. She then gets out of bed and goes downstairs for a drink, while calling her friend, saying that the horror film they had watched that night had creeped her out, and her friend tells her that nothing like what happens in horror films happens in real life, she then turns the light off and starts going back to bed, as she exits the screen, the focus is then on a dark figure standing at the window. It then sharply cuts, with a sound effect to create tension.
