Character by character
Origin and story
Literary usageWaking from a dream provides the image for suddenly recognizing what was previously misunderstood. The phrase appears in Xing Shi Yin Yuan Zhuan, chapter 53, when Chao Sicai thanks a woman for instructive advice and says he has awakened as if from a dream. In Lao Can You Ji, chapter 7, hearing an argument is similarly compared both to waking and to recovering from illness.
These are descriptions of new understanding, rather than accounts of actual sleepers. Related forms use 方醒 or 初觉 in place of 初醒. The cited literary examples show the established metaphor without proving a particular earlier author invented it.
