目を覚ます (to wake up)

The transitive idiom 目を覚ます, literally 'to wake one's eyes,' meaning 'to wake up.' Often kana-spelled 目をさます. Pairs with the intransitive 目が覚める ('one's eyes wake up'); the transitive form subtly frames the waking as an act. Distinct from 起きる ('get up,' physical rising), though both translate as 'wake up' in English.
