The kanji 夢 represents "dream". It signifies the state of mind experienced during sleep, involving images, thoughts, and emotions. It extends beyond the literal experience of dreaming to encompass aspirations, hopes, and ideals that one envisions for the future. The core concept is something imagined, whether while asleep or awake, that exists in the mind.

The kanji 夢 is a phono-semantic compound (形声文字). The upper part, 𦣻 (the simplified form of 𥥦), is a component related to "sleep" or "eyes closed." The lower part, 木 (tree/wood), might have originally been a phonetic component, but in modern interpretation, it's often viewed as representing the state of being in a world apart, as in a forest. The combination suggests the state of mind experienced during sleep or in a dreamlike state. The character evolved over time, simplifying from its older forms.
