For a moment, you thought that the entire world had been engulfed in darkness. That the sun had disappeared and left the Earth as a blank and desolate planet. You're eyes are closed, you scolded yourself. You were about to open them when the light sound of sobbing registered wherever you were.

"I-I can't do this anymore..." the voice came as a whimper. "I'm not ready to lose another one. Just please wake up [Y/N]!"

You wondered what Sans meant by I'm not ready to lose another one but then pushed it aside. Your mind wandered to the dream you had only a few seconds ago. For sure you recognized Sans, but he was a much colder version than the one you had gotten to know. Whoever Flowey was remained a mystery.

You assumed you had taken the role of Frisk and ventured through the Underground just like she had. Monsters were documented as mostly docile creatures from various news interviews. That reality made them cold.

It's just a dream, you shuddered. It's not your first nightmare.

But this one had been completely random with people you didn't recognize. As disoriented as dreams were, it was said that they were inspired by previous events that happened in your life and something underground wasn't an event you recalled.

Unless I experienced it in a different version of this reality, you thought ominously.

You couldn't take much more of Sans' sobs. "I didn't know you felt that way about me," you smirked mischievously and opened an eye, smirking at him. Sans almost fell back from the chair he was sitting in, his widespread smile slowly returning.

"I get BONELY after a while," he explained quickly, the blue tint returning to his cheeks. You couldn't suppress the smile that came. Sans immediately recognized the cause of this and turned away from you.

"I thought you were a BONE-afied expert at loneliness," you shuddered at the quality of the pun. Sans remained motionless and you realized that instead of a friendly pun, it had hit straight home. "I-I didn't mean it t-that way..." you muttered, placing a hand in his shoulder.

"It's fine [Y/N]," Sans smiles weakly at you. He adjusts his shoulder so that your hand no longer rests on it. "Come on," he mutters gravely, "we've got a job to do." You open your mouth to reply but notice that Sans is talking to the space two feet two his left where you assumed he hallucinated Papyrus' head.

Your heart plummeted and you slowly got to your feet, taking in your surroundings. You notice that it is snowing outside and a vast darkness seems to engulf most of the area around you except for the few lit candles that illuminated the house you were in.

"Sans, are we in Snowdin?" you ask, hearing the slight jangle of cash between the cushions. You reach into the cushions and reveal a handful of gold pieces. You return them carefully to their proper place and look at Sans, demanding an answer.

"Of course we are. Where else would we be?" he winks his left eye at you and then nods to a rock that stands on the shattered remains of what looks like a goat skeleton. "See? We even have company here."

"You are never alone Sans," the soft voice seemed to echo in the room. Sans immediately stiffened, recognizing the voice instantly. He continued to stare at the ground, knowing that it was all in his head. It had to be.

"SANS TORIEL IS HERE!" Papyrus cried happily and floated into Sans' vision. Instead of seeing a flying goat head, a tall goat stepped into view. She wore her traditional purple cloak adorned with the Dreemur crest symbol. A jagged line ran across her clothing, the same mark she bore in the genocide runs.

"You didn't die like that..." Sans muttered. [Y/N] remained unresponsive and he relaxed a little, comforted by the fact that she would not be disturbed by his conversation with his dead friends. "You're not real," he murmured, tears threatening to spill over.

Toriel raised a paw and brushed away a lone tear. Sans recoiled at the feeling of the fur brushing along his skull. They're not real. They're in my head...

Her eyes suddenly turned a dark red. Toriel's purple cloak turned into a red one with a black Dreemur crest. "You will join us very soon," she growled and motioned to a mirror.

Sans saw himself with a red gash along his chest with blood coming out of his mouth and onto his hands. The red eventually faded away into a much more demented version of himself. His teeth were filed to form what looked like fangs with a single golden one that glinted at him ominously. This version of himself stuck outs its hand in greeting. "Don't you know how to greet an old friend?" it winked.

This isn't real...

Undyne marched into view accompanied by Alphys and Mettaton. Wires jutted out in awkward angles as a result from a gash along his chest. Undyne herself was a completely different story. She seemed to be melting, droplets frozen in suspended animation. Alphys was frail, as if her entire body was made out of dust.

"Join us," they murmured in unanimous chant.

Sans grabbed his skull and let out a scream.

You heard Sans scream.

Whatever fantasy you had been in completely vanished as Sans fell from his chair and collapsed to the floor, twitching and muttering incoherent speech. "Don't you see them?" he spat, his left eye flaring from blue to red. Sometimes the two colors would mix to form a ghastly purple color.

"I don't see anyone..." you murmured. Sans began to mutter names that you recognized as famous monsters. Undyne... Alphys... Toriel... Papyrus....

Pain was like a knife that stabbed through your heart. The sight of the dead goat woman - Toriel you assumed - had triggered him into seeing other dead friends. "Sans listen to my voice," you said, your voice laced with sympathy.

Sans' head shot up and he looked wildly around the room. "[Y/N] are you there?" he asked, staring past you. His voice cracked. "I-I can't see you. I can only s-see them..." he began to thrash violently, his voice changing different pitches to match whatever dead friends his mind was making him see.

You could make out some of the dialogue.

"Join us."

"WE CAN SET YOU FREE!"

"Just give up. We did."

"H-How could y-you let me d-die?"

"You're a dirty brother killer."

It continued like this for several more minutes until Sans stopped suddenly and collapsed to the floor. Blue tears welled up in the corners of his eye sockets as sweat trickled down the forehead of his skull.

"Sans, can you see me?" you asked gently. Sans replied with a quick nod.

"Do you still see them?"

There was a pause.

And then a nod.

"All of them. I see all of them [Y/N]."
