I had a strange dream at night.
I dreamed about the classmate who had been missing for six years. His eyes were filled with tears and he asked me not to open the package.

The supernatural events that followed all came from this package.
The cat-faced woman wandering around the village late at night, the secret hidden under the blue lake, the doll walking around on its own in the middle of the night...
