In ancient times, both men and women had waist-length hair, which was very troublesome to arrange. If the rich have a good family, there are many servants at home, and their wives and young ladies have a lot of hair ornaments on their heads. They must comb their hair before going to bed at night. But if they are ordinary people, they mostly go to bed early at night to save money, so they don't comb their hair. This is also to save kerosene for my family, so it makes sense not to comb my hair at night.
The same is true of dreams. Although the ancients didn't use watches and other tools to indicate the time as they do now, they usually got up at dawn and started working. How come they have so much time to sit by the bed and listen to stories? This is a waste of time. Of course, another reason is that the ancients paid more attention to things. In the eyes of the ancients, good dreams are gone when they are spoken, and nightmares may become true when they are spoken, so people don't talk about dreams in the morning.
In fact, these are also related to personal living habits. For example, modern people like to comb their hair at night. After a busy day, their scalp tightened. After work in the evening, they wash their hair and have a good comb. I don't feel too good at all. I feel that my scalp has become much more comfortable. It's the same to say dreams in the morning, but it's much easier to say nightmares at night, and nightmares at night are mostly due to the pressure of life. This situation should be told to friends, so as to relieve the pressure.
