'HaHAhaHahA, YoU SuPID, IgNOrAnT, FoOL! YOu kNeW ThIS waS tO HapPEn, aNd yOu LEt iT!' Sans' voice croaked out, raspy and deep. The precious blueberry stares at the two of you with blood red pupils and an insane smile, twitching uncontrollably and spasming painfully, like his body is trying to reject the demon like the immune system with a virus. Soon everything is silent and the only thing that can be heard is your sobs and Papyrus' deep breaths. You shut your eyes and listen to Sans' screams of terror, unable to do anything in your power to save him. And the humans head turned toward you, showing you their blood red eyes and malicious smirk. And you pushed with all your might, screamed as loud as you could, but you could no stop that knife from raising above their head. perhaps later we can have a more appropriate battle!' But the human does not stop approaching Sans, and the closer they get, the more Sans seems to shrink. 'human, i do not like this type of confrontation. The human walks closer to Sans, making him look uncomfortable. It was as if something was holding you back. Your vocal chords wont work no matter how hard you try, and no matter how fast you run you don't get anywhere. Up ahead you hear Sans' voice, 'human! i appreciate you caring enough to want to fight me, but can we please not do this at three in the morning?' You begin to walk faster, and you start to run.

You tug harshly on Papyrus' sweater and say, 'You have to save Sans. Sans was in great trouble, and the sinking feeling in your chest told you that this wasn't going to end well. Your form begins to shake with fear and tears pricked the corners of your eyes. And they were Sans,ДЄnd the human from your nightmare. As you got closer and closer, you could see the silhouettes clearer and clearer, and the blob-like shadows soon morphed into distinguishable figures. You hoped that Sans was okay, you hoped everything would turn back to normal, and you hoped this would all clear up. 'LET'S GO.' Nodding, you walk behind him and hug your arms to yourself. A little farther ahead you see two silhouettes in the fog, but you didn't know who they were. 'YOU CAN LET GO NOW.' You slowly unwrap your arms from around his waist and remove your face from his sweater, looking around and seeing that you were no longer inside the house, but outside near a river. You close your eyes in fear and bury your face into his sweater, feeling yourself float and squeeze and press until you felt like you would throw up. 'HOLD TIGHT.' You do as he says and wrap your arms tightly around his waist, seeing the world around you begin to melt into nothingness. He suddenly grabs you and holds you close. 'H-he's not th-there!' Papyrus looks at you, his eye sockets growing dark and his face emotionless.

You run out of the room and toward Papyrus, with tears beginning to stream down your face. 'Sans, wake up.' The blankets shift slightly, revealing a pillow. Worried, you raise your voice and slightly shake the lump under the covers.

'Sans, you need to wake up now.' Still no response. Opening his door and making his way over to his bed, you quietly called out his name.

'GET SANS, NOW.' Nodding, you head upstairs quickly to wake Sans,but not really knowing why. Suddenly the front door opens and slams shut, and you turn around to find Papyrus holding the door shut with a frightened expression. It was just a dream, Sans is fine, everything is fine. You sit down on the couch and let out a breathless laugh. Closing the door silently, you make your trek back downstairs. Letting out a shaky breath, you relax slightly seeing the lump on a race car bed. Stopping in front of a door with tape reading 'keep out!', which you instantly knew was Sans', you sucked in a breath and quietly opened the door, peeking inside. This is Real.Once you had calmed yourself down, you quickly rush up the stairs.
