After a near-death rescue, Lu Chen gained the ability to enter other people's dreams.
In dreams, he can take away memories, items, and even power; the price is that every time he wakes up, he forgets an important thing in reality.
Until one rainy night, deep in the nightmare of a suicidal patient, he saw a girl who shouldn't exist.
Her name is Shen Zhiwei. She has been in a coma for three years in reality, but appears in everyone's dreams.
She told Lu Chen: Don't believe the door in the dream, don't go to the seventh floor, and don't try to wake her up.
But as more and more people died in their sleep, the whole city began to be swallowed up by nightmares, and Lu Chen discovered that the dreams that humans have every night have long been connected into an endless world.
And Shen Zhiwei is the night watchman trapped in the deepest part of the dream realm.
When the boundary between reality and dream completely disappears, when Lu Chen will forget even the name "Shen Zhiwei", he can only carry a lamp brought out from his dream and walk towards the seventh floor where no one wakes up.
"What if you don't remember me when you wake up?"
"Then please, dream of me again."
