To be honest, if he had consumed the "mutated parasite" prior to developing "super sensory state" and gaining the "sixth sense", he probably would not understand the information he perceived during sleep, and would not have taken it seriously.
But now, Xiang Kun clearly knew that the information he received was likely the "memory" of the "mutated parasite" he had consumed.
However, these "memories" were not composed of visual, auditory and other information familiar to humans like the memories of Guo Tianxiang or the Giant Owl, but rather a special kind of sensory information that is hard to describe with words.
In fact, when he consumed the "mutated spider" in the Qinling Uninhabited Area, the memory information that Xiang Kun received was also quite distinctive. But those memories, although unique, were still within basic understanding, allowing him to immediately judge what he was seeing.
