Synonym discussion
Sense: adverb/1
Dreamily, wistfully, absently, and vaguely all describe doing something without full mental focus, but they differ in tone. Dreamily carries a warm, pleasant feeling — your mind is somewhere nice, not just blank. Wistfully adds a bittersweet touch of longing, as in 'She gazed wistfully at the empty house where she grew up.' Absently is neutral: it means your attention has wandered, but says nothing about what you are thinking about — just that you are not paying attention. Vaguely suggests haziness or lack of clear memory or understanding, as in 'He vaguely remembered meeting her before.' Use dreamily when the person is lost in a pleasant daydream; use wistfully when nostalgia or desire colours the scene; use absently for simple inattention; and use vaguely when something is unclear or indistinct.
Etymology
Formed from 'dream' (from Old English drēam, originally meaning 'joy, pleasure, music') plus the adjective suffix '-y' to form 'dreamy', then the adverb suffix '-ily'. The modern sense of 'dream' as a series of thoughts during sleep developed in Middle English, and 'dreamily' followed as a natural adverb describing a state like that of dreaming.
