Human beings' dreams were mysterious and subtle, which was valuable. There was a superstitious statement that a dream signified that one's soul hung out when one fell asleep, and the dream was the journey of the soul. In such a scientific era, it was just a joke, but the magic of dreams couldn't be ignored.
The most interesting and obvious feature was the connection between dreams and reality. Most of the time, the human dream continued into reality, and it was a subconscious imagination. Put simply, when humans are half asleep and half awake and connected with the things or people in reality, for example, someone calls them and asks them to do something, they only have short-term memory. When they fell asleep again, this kind of memory was replaced by their dream, while the dream would have something to do with the words or the order.
It was just like compensation. Human dreams remind them to finish something and tell them in the form of a dream.
