I just had the strangest dream and need help deciphering it. It started with a white van speeding down a packed highway when suddenly, a commercial plane carrying a fucking massive bucket of water with a big chain poured the contents onto the road which made a huge tsunami-like wave. Right when the van crashed into the oncoming wave, everything went black. Marine, Pekora, and Rushia are sitting quietly in the back of the still van in total darkness. The back door is literally ripped off by Luna with her bare hands and the sudden wave of light reveals a helicopter in the air with Subaru parachuting out towards them. Luna, blocking them from leaving the van, smiles menacingly and says "Okaeri."
Surrounded by destroyed cars and rubble, the van is the only vehicle left unharmed for some reason. Three black SUVs roll up in formation and park just behind the van. Fubuki steps out of the car in the center driven by Matsuri with sunglasses. Luna steps aside and bows as Fubuki makes her way into the van. Marine signals Rushia and Pekora to stand behind her. Fubuki grabs Marine's hand and places a tiny, worn down grey key and a shiny golden key in her hand before whispering something in her ear. Marine is shocked but is able to contain her anger. Fubuki steps back and says with a warm smile on her face, "Anata o matteimasu." After a long pause, Marine smirks and declares "Go to hell!" Disappointed, Fubuki turns around and mutters "Ah sou" before a dark figure instantly appears behind Marine and slashes her throat. Marine collapses onto the ground and Pekora starts to scream hysterically.
As Luna and Fubuki enter the SUVs (I don't what happened to Subaru), the unknown person hesitates, turning to look at the trio. The character is revealed to be Haachama carrying a boxcutter dripping with blood. A mysterious voice from the back of the car calmly orders through a voice changer, "Ikou." Haachama enters the car and they drive away. Pekora is still wailing and Rushia, half-covered in blood, is staring at Marine's lifeless body in her arms with a blank expression on her face. Rushia slowly raises her head and gives off the faintest chuckle.
And that's when I woke up. What does it all mean?
