Rattled (Sans X Reader)

Waking AGAIN

When you woke again, you found yourself on the skelebros's couch once again. This time, you didn't just have a single sheet, there was actually a few good blankets. The smell of spaghetti drifted in from the other room. Suddenly, you felt the presence of somebody, and their arm was wrapped around you. You shifted your head a bit to see Sans. Why was he..? Never mind. It wasn't like you could move, or else you'd wake him up. You stay there for about ten minutes. Honestly, you were weirdly comfortable. You definitely weren't used to this, but accepted it all the same. Then you noticed his breathing was getting kind of weird. You decided to not disturb him unless it got worse, at which point you would try to wake him up. I mean, he was probably just in a weird point of a dream or something. By now, you smelled fresh tomatoes being cooked. It actually smelled really good! By now, Sans has started whimpering. Yeah, you should probably wake him up..
You shook him a bit. "Sans, are you OK?" He didn't wake up. You begin to hear footsteps, getting louder and louder until Papyrus was at your side. You nodded in Sans' general direction and he nodded back.
"Sans, wake up!"
That's when Sans finally came to consciousness and started crying. You weren't sure how to handle this. You knew how to comfort humans, but you didn't know exactly what to say to Sans. Sans buried his face into your shoulder (For some reason, you still aren't sure why). You hesitantly wrapped your arm around him to try to comfort him. After a while, he seemed to get a little better.
"SANS, WHAT HAPPENED?" Papyrus asked, back to his normal tone of voice.
"N-n-nightmare.." You could tell that he was barely able to respond. You could tell by Papyrus' facial expression that he was going to be asking about it later. You didn't know what to do. You were still ashamed about the spear incident. You say there a bit longer, and Papyrus eventually left to make some, "DONT BE UPSETTI SPAGHETTI!" as he had put it. You couldn't leave, as Sans hadn't removed his face from the shoulder face plant.
"(Y.N), please... don't hurt Papyrus."
"Of course I wouldn't, why would I?"
"JUST PLEASE!" You could tell he was on the edge of crying again, and it took a while to even get to this point. Maybe this was an explanation of his nightmare, to some extent? Did you kill Papyrus in his dream? You decided to find out later. He buried his face back into your shoulder. You slowly felt yourself drifting off to sleep..
