Zhao Anan was a person who had a good night's sleep and rarely had dreams. But every time she had a dream, it would be a dream of her disease. And every dream was very similar, so real that it made her feel scared.
Most of the time, dreams could reflect a person's mental state, thoughts, and health.
If a person kept dreaming about falling off a cliff, it didn't mean that the person's career was going downhill. It just meant that the person had a heart problem and needed to find a doctor for treatment.
The simplest and most obvious example of a dream reflecting reality was that if one's feet were exposed when sleeping without a blanket, then one would dream of standing in cold water or leaving the house without wearing shoes.
Of course, not all dreams had a practical meaning. You dreamed that you picked up a gold ingot, but you wouldn't really pick up a gold ingot the next day. In this case, you were usually crazy about money.
