I wasn't playing the game but I was watching someone else play Deltarune and they were in some weird place that looked like the school, but it had no music and it was all backroomsy or whatever with like sprawling maze like hallways that were filled with messy like trash art supplies and whatever, I think Kris had their Dark World appearance and after awhile, they finally got out of the place out of some really dark ass pathway to the place and ended up back in hometown next to what I think is qc's diner, playing the school theme for some reason. And then after walking around nest the diner for a bit they opened the menu which for some reason became a scrapbook thing and these textboxes from Berdly appeared, I don't really remember much of what he actually said but his portraits were all severely beaten up and covered in red blood. He did his more goofy faces here too and they were also beaten up and covered in blood too. A lot of the portraits are of him seeming remorseful and guilty about something. This really freaked me out in my dream if I remember.

afterwards, they closed the menu and now the place is strewn with Berdly corpses everywhere and Kris was suddenly wearing a McDonald's looking uniform, with no mouth and with ponytails. And they quickly went back into the dark hallway, they were now back in the weird dark school and they continued to explore the the place until they reach a horizontal hallway were suddenly some pluey-like entity (not THE pluey just something that looked like the green creature interpretation) and the way the appears was like they got poured into form or something, like some liquid dripping to an invisible cookie cutter thing. Other then what may or may be a weird routey battle afterwards I didn't remember what happened after and I woke up a bit after. Also I think I was watching mysticslime but there wasn't any commentary in the video.

Yea thats the dream, if you aren't in the fandom you probably not gonna get what im even talking about here
