Despite enduring all sorts of inhuman torment, the little girl remained kind, and she personally recounted to Gao Ming the events of the past, sharing with him much information about nightmares.
Every nightmare in the world is unique, condensed from the desperate moments of the dreamer's life, imprinting reality into illusions.
Perhaps it was the accumulation of too much pain that the illusions of despair precipitated into a true form, transforming into a deep sea that cannot be seen, but definitely exists.
The little girl experienced it firsthand. She said that nightmares are roughly divided into three layers. The first layer of the nightmare is the most common, also known as a shallow nightmare. Anyone could experience it, as it is entirely a projection of reality. All the elements within the nightmare, no matter how strange or absurd, can be mapped to events that occurred in reality.
