Spiral Of Dreams (Nightmare Sans x Reader)
You have been tormented for three months now by nightmares about the dark skeleton with four tentacles. You have gone to the extent of trying to stay up all night, but Sans has other plans. Sans. That's what he told you his name was after he took you to the nightmare realm. But this is dangerous for humans to be conscious in the nightmare realm. Everytime you go to sleep, you are taken right back there, and you soon find yourself unable to decipher what is reality and what is the dream. All you really know is that, in one, you wake up when you die. And in the other, you stay dead when you die.
But Sans won't let that happen. Because even though you're his prisoner here, he enjoys your company. Besides, without you, he'd be very lonely. So he'll always be there, to tell you if you're awake or asleep. Whether you'll wake up or die. And he'll do his best to protect you from the real monster of this story.
