寐寤（上彌庇反下吾固反韓詩寐息也玉篇眠熟也蒼頡篇覺而有言曰寤前文已具釋說文並從㝱省未吾皆聲也或有從穴或從忄作寐寤皆非也上從宀音綿左從爿音墻）。

Sleeping and waking (meiwu 寐寤: the first character is [pronounced with the] fanqie mi-bi 彌庇; the second is [pronounced with the] fanqie wu-gu 吾固. The Han commentary on the Shijing says: “Mei 寐 means to rest.” The Yupian says: “Sleeping deeply.” The Cang Jie pian says: “Waking and having speech is called wu 寤.” It has already been fully explained above. The Shuowen states that both are composed of an abbreviated 'dream' [component] 㝱 with wei 未 and wu 吾 as their phonetics. Some write them with the 'cave' classifier (xue 穴) or the 'heart' classifier (xin 忄), which are all incorrect. The upper part is composed of 'roof' (mian 宀, pronounced mian 綿); the left is composed of 'half-tree-trunk' (pan 爿, pronounced qiang 墻)).
