《黄帝内经·素问·方盛衰论》
三阳之脉悬绝，三阴之脉细微，就是所谓少气之侯。肺气虚则梦见悲惨的事物，或梦见人被杀流血，尸体狼籍，当金旺之时，则梦见战争。肾气虚则梦见舟船淹死人，当水旺之时，则梦见大火燔灼。
肝气虚，则梦见菌香生草，得其时，则梦伏树下不敢起。心气虚，则梦救火阳物，得其时，则梦燔灼。
When the pulses of the three Yang channels are suspended and the pulses of the three Yin channels are thin, that is what is called a Shao Qi sign. When Lung Qi is deficient, people will dream of tragic things, or dream of people being killed, blood flowing, and corpses everywhere; when Gold is strong, they will dream of war. When Kidney Qi is deficient, people will dream of people drowning in boats; when Water is strong, they will dream of great fires.
