In 'current homestuck time', are the dream bubbles still around? Like, they don't disappear right? All the dead/doomed selves are just.. gonna forever be in the bubbles?

Time is weird because technically speaking the Furthest Ring should have no concept of Time, and there may still be the possibility of you being in an area of the Furthest Ring that was temporally locked further back than the ‘current’ time.

That being said?

Everything’s breaking apart, Jim. Dream Bubbles aren’t going to last, if there’s any left at all.
