睡寤（上垂累反蒼頡篇云欲臥也說文坐寐也形聲字也累音類下音悟毛詩傳曰寤覺也覺音教說文寐覺而有言曰寤從㝱吾省聲或作害略也經從穴從心作𥧝非也正體從宀從爿）。

Sleeping and waking (shuiwu 睡寤: the first character is [pronounced with the] fanqie chui-lei 垂累. The Cang Jie pian says: “Desiring to lie down.” The Shuowen says: “Sleeping while sitting.” It is a phono-semantic character; lei 累 is pronounced like lei 類. The second character is pronounced wu 悟. The Mao commentary on the Shijing says: “Wu 寤 means waking.” Jue 覺 is pronounced jiao 教. The Shuowen says: “Waking from sleep and having speech is called wu 寤. It is composed of the 'dream' [component] 㝱 with wu 吾 as the abbreviated phonetic.” It is also abbreviated as 害. In the sūtra text it is written with the 'cave' classifier (xue 穴) over the 'heart' classifier (xin 心) as 𥧝, which is incorrect. The standard form takes the 'roof' (mian 宀) and 'half-tree-trunk' (pan 爿) classifiers).
