In Islamic culture, this crescent moon is very important. It's used as a symbol to mark the beginning and end of "Ramadan," the fasting period, so it has deep religious and cultural meaning.

Besides symbolizing night and dreams, it also pairs well with mystical themes like magic or fantasy. That's why you often see it in fairy tale books, animation, and games. It's also frequently used in K-pop idols' mystical concepts or the titles of dreamy music videos.
