A nightmare that never ends, a warning from the grave.
He was trapped in the same strange dream every night: a huge empty art gallery, the pale corridors stretched endlessly, and the hanging picture frames were filled with nothingness. The only "live" thing was a girl in a white dress who always gave him a hollow smile. This repeated nightmare gradually eroded his sanity, until that rainy night, he bumped into her in the dream on a street corner in reality.
The girl was pale and frightened, grabbing him coldly, leaving a hoarse warning like thunder: "Don't fall asleep again - that art gallery is my tomb!"
The next day, the news broadcast: An underground art gallery that had been buried for many years was resurfaced. One of the female skeletons was holding a broken diary in her hands. On the first page of the diary, a shocking line of writing reveals the source of all nightmares:
"If he dreams about you, he'll be the next victim."
Now, he understands. It was not a dream, but a preview of death. The art museum is the tomb where the past is buried, and it is also a brand new coffin prepared for him. Every time he closed his eyes, he might slide towards the eternal cage guarded by that pale smile.
When the dream core whispers and the death rattles, he must stay awake, struggle to survive on the boundary between reality and illusion, and uncover the terrifying truth buried in the art museum. Otherwise, he will become the next static exhibit in the endless corridor.
Concept: The art gallery in the nightmare is her forgotten tomb; and every time I fall asleep, it becomes a ritual approaching death.
