Scenes like these were everywhere. These were the memories of the dead during their dying moments as they were remembering their lives and their feelings.
The memories were overfilling, so much so that the second Heavens was fully packed with them. Since the birth of the cosmos, there were countless living beings that lived and countless of them dead. This has caused the burial ground to be filled with their memories.
It was impossible to avoid all of them while traveling through the second Heavens. For example, Zhong Yue himself accidentally touched a scene himself and he suddenly found himself becoming a little baby. Then, he experienced the baby's life as 'he' grew into a child, a young man, an adult, and finally die of age.
The life of the memory owner was compressed into a few moments and forced into Zhong Yue's mind and made him experience the memory owner's life in just seconds.
