Dream is a physiological phenomenon and a psychological activity during sleep. The ancients believed that dreams have a reason, and the human soul is revealed by the gods during sleep. Westerners believe that it is the satisfaction of subconscious desires and the main way to release pressure. There is another saying in China called "thinking about it day and night". Modern medicine has also confirmed that dreams are beneficial to human health, and dreamless sleep is of poor quality. If you believe, you have a dream; if you don't believe, you don't. We should keep a peaceful mind. No matter what your dream is, you should face the real life seriously, and you should not be happy because of a good dream, but sad because of a bad dream.
When we wake up, we all want our dream to come true, so it is called "dream come true", which has become our long-sought belief. People with dreams will have a real life, and dreams will become the driving force.
