Infinite Dreamcore Amusement Park

This is a dream that can "spread."

A tower with no visible end, a carousel that spins forever, a garden covered in green leaves, an empty swing swaying by itself, and a bottomless pool...

At some point, people began falling one after another into bizarre, absurd dreams. The dreamscape was boundless, with no way out.

People on the forums called this phenomenon "Infinite Dreamcore."

As time passed, the strange phenomena in the dreams grew worse. Those "swallowed" by the dreams never woke up again.

To find the "exit" in their dreams, people began exploring the dreamscape.
