There is a monster in your house. Shiny new deadbolts adorn your small home like ornaments, each checked and secured religiously. You search the entire house every night to no avail, but whenever you drift off, you wake to find it again. Something slithering up behind you, whispering in your ear, stroking your back. You'd scream if you could. It does something before you wake, you're certain, paralysing you but for opening your eyes. Since the first night, stock still with something creeping at the edges of your vision, you keep your eyes shut. You had confessed to your closest friend after days of terror, only to be brushed off as some sort of mental case, "sleep paralysis", they said. Like you're that weak, to be some sort of schizo. You don't need them. You decide to stop being such a pussy, and face this fucker head on. That night, you open your eyes.
You vaguely recall people going on about how horror movies always disappoint once they reveal the monster, because the reality could never live up to your imagination. They were wrong. Every last inch of the thing haunting you for the last two weeks is worse than you could have imagined, and you had time to imagine a lot. A black carapace dripping with viscera, a collage of faces, claws, and teeth. Things squirm and twitch as it hangs over you, telling you in a rasp that tomorrow, that's the night. The night it will feast. You freak out, unable to move for what seems like  hours on end, screaming only in your own head. Excruciatingly slowly, you regain control of your own body, finally pulling yourself from the puddle of sweat and piss that is your bed. Desperate, you call a friend, and start sobbing to them over the phone.
They listen, patient as you babble your way through your story, and calmly tell you they're coming over. They arrive at your house, and talk to you thought the barred windows as you unlock the door, telling you they understand what you're experiencing; Sleep paralysis, and the hallucinations commonly associated with it. Eventually, they talk you down from your panic, promising they'll watch over you all night, and jolt you up if you open your eyes but can't move. Finally feeling safe, you pass out.
You wake to find your friend snoring softly in a chair next to your bed, and the monster coiled around them, thanking you for bringing them an extra meal. As the creature sinks it's fangs into your only hope of survival, you jolt up screaming, and trigger, oblivious to your friend's frantic assurances that you are alright.
