I'm not sure. Maybe it's inspired by some real-life events or fictional concepts. But without more details, it's hard to say for sure.
Well, 'Dreamer' could be based on a variety of sources. It might draw from myths, legends, or even personal experiences of the author. Or perhaps it's a blend of different ideas to create a unique story.
To be honest, I don't know exactly what 'Dreamer' is based on. It could be based on a historical period, a fantasy world, or a social issue. Without further information, it's difficult to pin down.
