<Once a Dreamer> portraying two children holding hands with each other, the only person each can rely on, at dawn, endless darkness in the room with no light but only moonlight sneaking in through the window. However, this is the viewer’s point of view, not the children's, and they might have a big adventure of imagination inside of the paper bag they are wearing upside down on their head. We all had once experienced this unforgettable moment, when nothing was scary and everythings seemed so dramatically exciting. This painting depicts one's nostalgic moment.
