My horror movie idea

Ria, a typical teenage girl from the small town of lowestoft, was spending the evening at her boyfriend's house. At about half midnight, Ria decided it was time to leave as they both had to be up early that morning. She said her goodbyes, got in her car, turned her music up and began her 25 minute journey home. She was singing away and tapping her thumbs on the the steering wheel when something in her rear-view mirror caught her eye. Her head sparply turned towards it and she had a closer inspection, nothing was there. She shook it off and carried on driving. Wary of what she saw, she turned down her music. As she drove along the deserted, dark roads, she could feel soft, warm air blowing her hair forward on the right hand side of her face. She frantically checked that all of the windows and doors were fully shut, they were. She couldn't understand where this warm air was coming from, she turned her music off. She began to hear faint sounds of someone breathing near her head. She inhaled deeply through her nose, her eyes widened and she pulled over immediately. She got out of the car straight away without even turning behind her to look in the backseat, she turned off the ignition and slammed the door. She figured if there was something or someone in her car that she would be able to see them through the window, and at least then she would be outside of the car. Her palms sweating, she looked closely through the window, she saw nothing, she opened the boot, she saw nothing. She slammed the boot shut and looked back along the road she had driven down, she put her hands on her hips as she breathed a sigh of relief. Before she knew it, she heard her engine start, she whipped around and watched her car be driven into the woods nearby. In a desperate attempt to get her precious car back and without further thought, she found herself sprinting as fast as she could after her car. The ground was bumpy and uneven and as she tried to keep up with the car she stumbled. She didn't give in, she could hear the sound of her cars engine so she knew it wasn't far away. She thought maybe the driver had freaked out, left the car and ran off, why could she still hear the car? As she got closer the car got louder and she could see the headlights peering through the branches. She finally got to her car and was horrified at what she saw and was possibly about to happen to her...

My group decided to go with my idea for our horror teaser trailer.
