First of all, yes there is one thing that seems to be a typo but isn't. (I'll talk about it if asked.) Buuuut... I've come up with backstory, which refuses to collate into an actual prequel/sequel flash fiction -_-
Wrote his at least a year ago, came up with the backstory soon after, and then it... left me alone for the most part.
Enjoy. Or don't read. It's all good.
She dreamt of monsters of the deep, leviathan gliding through the water far below her. The creatures were too large to still exist; she understood this fact without being able to see down into the murky-black depths where they swam.
The next wave crested at an unbelievable height, and she froze, sinking before the water came down, dragging her along. She would drown. Worse would happen if they caught her...
The details fell away as she woke, her breaths loud I. Her own ears, a buzzing in her head, sweat-slick and sick. Her vision adjusted to the deep dark of an empty house, all the lights off and all the curtains drawn. She still saw nothing, yet made no move to reach out for the lamp, to drench the room in light tinted an unnatural yellow by the bulbs.
She sat, acted as if she were a statue, waiting for her heartbeat to slow, to become even and painless, for the drum-beat pounding through her veins lost it's quick, deafening quality.
Soon - too soon and not soon enough both - she was able to get to her feet and lurch to the bathroom. Her face was pale white in the mirror, devoid of it's normal slight pink flush. Her hair was greasy, plastered to her head, and she pushed back a small clump, propping it behind her ear.
She splashed water on her face and felt no better and just as restless as before.

The next day she and her friend stood on the beach, the same chill running down her spine, the same sensation of smothering, drowning, making her unsteady on her feet. The sky was the same neutral gray, the water reflecting the same gloomy color.
She kept her jeans on over her bikini bottom, watching her friend smirk and strip down, shouting something and laughing as she ran towards the calm water. How odd to see the storm building above, to feel the rain so mild at first, and the sea still as if waiting for the proper moment to attack.
