Authors note:

Takes place while the trolls and humans (Dave and Rose, at least) are on their way to the new post-scratch world. AU for a few reasons:
1. Dave never show Gamzee the video that made him doubt his faith, so he never went fully sober and kill anyone. However, Eridan still killed Feferi and Kanaya, Vriska still killed Tavros, Kanaya still came back as a rainbow drinker (troll version of a vampire) and killed Eridan, and Terezi still killed Vriska, so not much else changed.
2. Because Gamzee never went on a murdering spree, Nepata and Equius are still alive.

And a few other notes:
3. Sollux and Aradia are alive, just not sure where they are (still not on the asteroid with the others)
4. Just to be clear, the characters here are Dave, Rose, Karkat, Nepeta, Kanaya, Terezi, Equius, and Gamzee.
5. Also just to be clear, we won't be seeing much of the humans after the prologue. Maybe if I change my mind later but no promises.
6. I will use the trolls quirks when typing dialog for them, but I won't use Nepeta and Equius's prefixes (:33 and D -) because that just looks off in the middle of a normal paragraph (the quirks look weird enough).

The MLP universe is pretty much the same.

Terezi's voice blared on the speeker, "DR34M BUBBL3 4PPROCH1NG! TH1S ON3 SM3LLS R3ALLY B1G, W3 M1GHT B3 1N 1T A WH1L3!" she announced.

"GREAT, JUST WHAT I WANTED," Karkat grumbled. He really didn't care much for dream bubbles. He didn't mind them as much as long as he got to see their dead friends, but often times they didn't.

"aww karkitty, it's not that bad," Nepeta said, looking at Karkat with sad eyes. She found the dream bubbles fun.

"WHATEVER," he replied discontented.

"CoMe On BrO, yOuR AlWaYs So StReSsEd. JuSt ReLaX," Gamzee said while eating his usual soper slime pie.

"WHATEVER 'BRO'," he replied. "STRIDER, YOU CAN'T POSSIABLY LIKE THESE THINGS, RIGHT?" he said looking at the human boy.

"No, I like them," Dave said smugly. He really didn't care either way, he just liked to annoy Karkat.

"And I actually find them interesting," Rose added.

"I DIDN'T ASK WHAT YOU THOUGHT, LALONDE, I ASKED STRIDER." Katkat snapped at her, then turned to Equius, "WHAT ABOUT YOU, YOU HAVEN'T SAID ANYTHING YET."

"I don't think I should talk to you about such matters, lowb100d," he replied. In truth, he liked the dream bubbles, they allowed him to live his more embarrassing fantasies.

"UGH, POMPOUS BLUEBLOOD." Karkat was getting more irritated.

"karkitty, you're so cranky, what's wrong?" Nepeta asked.

"I JUST DON'T WANT TO BE STUCK IN SOME BUBBLE FOR WHO-KNOWS-HOW-LONG. IT'S BAD ENOUGH I'M STUCK ON THIS ASTEROID FOR THREE YEARS. HOW LONG IS THREE YEARS ANYWAY?"

"About 156 weeks." Rose answered.

"FFFFFFFFFFFFUUUUUUUUUUUUUUU"

"Jeez man, calm down," Dave was starting to get annoyed by Karkats rage.

Suddenly, Terezi's voice blared across the speaker again. "W3'R3 4BOUT TO 3NT3R TH3 BUBBL3, JUST THOUGHT 1 SHOULD W4RN YOU."

"GREAT, HERE WE G-" Karkat was cut off by the asteroid suddenly shaking violently as it entered the dream bubble.

"Whoa- Ahh- Gah- Ow-" they all said as them stumbled around the room, hitting walls, furniture, falling to the ground. This wasn't normal for the dream bubbles, but this one was very large. Furniture began to fall around them and all of them hit the floor. The combination of the violent tremors, the furniture falling around them and the usual confusion from entering dream bubbles had knocked them out.
