Dreams were a very magical thing. As the saying went, " what you think in the day, you dream at night. however, people could not really control what they dreamed of at night.
Furthermore, people who were dreaming would not know that they were in a dream. All the feelings in the dream would be treated as reality.
It was like a world that had been created for a short period of time.
Legend had it that if a person died in a dream, there was a possibility of giving birth to a ghost called " kun.
It had the ability to enter and exit other people's dreams, and could absorb Yang Qi from people's dreams to cultivate. After one's Dao attainment deepened, one could even forcefully pull people into a dream.
Such ghostly beings rarely appeared, but once they did, they were very difficult to deal with. This was because it was easy for it to harm people. As long as they were in a dream, no one could fight against it.
