人身上的睡意
最直接的一層：被拉的是人自己。
adjective · B2
Feeling so tired that your eyes keep closing and you could fall asleep where you are, even when you are trying to stay awake. Often used about how medicine, heat, or a big meal leaves you.
昏昏欲睡
核心畫面
One picture can carry all of this: coming down. Sleep has not arrived yet, but it is pulling. The head dips, the page stops moving, sounds arrive a second late. From there the word can stay on the person who feels the pull, or move onto whatever is doing the pulling - a hot afternoon, a silent room, a of cough syrup.
可以想成一個畫面：眼皮正在往下掉。人還沒睡著，但睡意已經在拉了——頭一點一點的，書頁停在同一行，別人講話你慢半拍才聽…更多收起
可以想成一個畫面：眼皮正在往下掉。人還沒睡著，但睡意已經在拉了——頭一點一點的，書頁停在同一行，別人講話你慢半拍才聽懂。這個字可以停在「被拉的人」身上，也可以挪到「正在拉的東西」身上：悶熱的午後、安靜的房間、一匙糖漿，都可以接手這個字。From the word’s history
Wiktionary records drowsy as drowse plus -y, and points to Old English drusian, to droop or become languid. The drooping is the same movement as the eyelid in the core image.
依 Wiktionary，drowsy 是 drowse（打瞌睡）加上 -y；它同時指出更早的古英語 drūsian 有「垂下、變得無力」的意思。那個「垂下」跟核心畫面裡眼皮往下掉是同一個動作。

把睡意帶出來的東西
同一個畫面，視角從「被拉的人」換到「拉的那一方」。人可以不出場，睡意留在場景或藥瓶上。
adjective · B2
Used about a place, a time of day, or a scene that is so quiet and slow that it makes you feel relaxed and close to sleep. Here the afternoon, the town, or the heat is drowsy, not the person.
靜得讓人想睡的；懶洋洋的
