She heard a striking knock on her bedroom door.
This would be, in some cases, totally normal for some people. Who knows, maybe your parents want to make sure that you're okay because you haven't been out of your room for a whole day. Could be your roommates who want to ask you a question or invite you to another one of their many parties.
But seconds later of hearing that, she felt a shiver roam over her spine. She felt how her heart came to a stop and from a moment to another you could hear how blood rushed to her limbs. She instantaneously jumped off her comfy bed that at that moment seemed to make a painfully loud noise, letting her book fall onto the silky sheets. Eyes big wide trying to capture every glimpse of light. Her lungs couldn't catch up with the beating muscle on her chest making her breathing quicken. Her sweaty palms searched for any long and or sharp object that she could use to at least make her feel some kind of vain protection and imagine not being this helpless against whatever is behind that white wooden door.
In this case, it wasn't some case. It was 2:48 in the morning, a time when she would still be spending the little hours she has to sleep, reading fantasy books that make her daydream in the middle of class. The only time that she has for herself.
Alone
Because, yes, she lived alone in her student-wage-worth apartment. Apartment 518, on the fifth floor.
