Historical forms of the character 夢
Shang	Western Zhou	Warring States		Shuowen Jiezi (compiled in Han)	Liushutong (compiled in Ming)
Oracle bone script	Bronze inscriptions	Chu slip and silk script	Qin slip script	Small seal script	Transcribed ancient scripts

In the Oracle bone script, a pictogram (象形) or ideogrammic compound (會意／会意) – a person (人) lying on a bed (爿), sometimes with restless hands (compare the oracle-bone character for 丮) and sometimes with the eye (目) emphasized.

In the Bronze inscriptions, the eye (目) has eyebrows above it (compare 眉), and the person's body is attached underneath, now written as two dots on either side. The bed is no longer present, and instead 夕 (“moon; night”) has been added.

In the modern form 夢, the eyebrows are written 卝, the eyes are written 罒, and the person's body has become 冖, while 夕 remains on the bottom.

According to Shuowen, it is a phono-semantic compound (形聲／形声, OC *mɯŋ, *mɯŋs) : phonetic 瞢 (OC *mɯːŋ, *mɯŋ, *mɯŋs) + semantic 夕.

From Proto-Sino-Tibetan *(s/r)-ma(ŋ/k) (“dream”); compare Tibetan རྨང་ལམ (rmang lam, “dream”), Chepang माङः (“dream”), Proto-Lolo-Burmese *s-makᴴ ~ *s-maŋ¹ (“dream”), Mizo mang (“dream”), Japhug tɯ-jmŋo (“dream”) (STEDT; Schuessler, 2007; Zhang, Jacques and Lai, 2019).
