arāmu

Japanese has a specific word, 二度寝 (nidone), for the act of falling back asleep after an alarm has already woken you up.
In Japan, some people use 'wake-up calls' provided by hotels, which are referred to as モーニングコール (mōningu kōru).
The concept of waking up is often associated with the phrase 目が覚める (me ga sameru), meaning 'the eyes have awakened'.
