梦幻 (mèng huàn) is an adjective meaning 'dreamlike' or 'illusive'—evoking the soft, hazy, and often beautiful quality of dreams. The first character 梦 means 'dream', carrying connotations of imagination, longing, and subconscious experience; the second character 幻 means 'illusion' or 'mirage', suggesting something unreal, fleeting, or magically transformed. Together, they form a compound that emphasizes aesthetic wonder tinged with impermanence—often describing scenes, atmospheres, or feelings that feel too beautiful or strange to be real.

This word appears frequently in literary, artistic, and descriptive contexts: travel writing about misty mountains, poetic descriptions of starry nights, or marketing language for luxury experiences (e.g., a 'dreamlike resort'). It carries a gentle, positive tone—not negative like 'delusional', but rather wistful and enchanting. While it can occasionally imply unreality in a cautionary sense (e.g., 'a梦幻 plan'), this usage is rarer and usually signaled by context.
