Papyrus doesn't dream very often, largely because he doesn't sleep very often. Even before leaving the underground, he spent most nights awake and doing things. That hasn't changed, not with the wider variety of things to be doing in the human world. So it's with some confusion that he has no idea where he is, or what is going on.

He walks through the halls, looking for signs of how he got here, or other people, or just an exit. The strange tiled floors, the awful lighting... It's like no place he's ever seen before. Too bad he doesn't watch more science fiction. MTT's set designs are always a little flashier than this, and don't help him to recognize it.

The sudden crashing sounds are the first sign of life, and he jogs around a corner to find the culprit. It's almost not a surprise, to see Sans knocking things on the floor.

"Sans!" Papyrus throws his hands up in the air, exasperated almost beyond words. "It's bad enough you make a mess at home, but doing it in somebody else's... place! Who do you expect is going to clean this up?"

It's sure not going to be Papyrus. Not when it's bad enough that his brother leaves his literal dirty laundry around, and doesn't even follow helpful reminders to take care of it.
