I'm not sure as I haven't read the 'dreams in darkness novel' specifically. But typically, the main characters are those who drive the plot forward. They could be people who are in some sort of struggle against the 'darkness' mentioned in the title, perhaps a young hero or heroine trying to find their way in a difficult world.
The main theme could be the exploration of the human psyche in difficult situations. Since it's called 'dreams in darkness', it might deal with how people face their inner fears and hopes when surrounded by hardships.
Since it's a novel about 'darkness', there could be a character who is initially innocent but gets drawn into the dark world. There may be a mentor - like figure who tries to guide this character out of the darkness. Or perhaps a group of characters with different motives, some good and some bad, all interacting in the setting of this 'darkness' that the novel portrays.
I'm not familiar with this particular novel. However, it might have a group of characters. There could be a mentor figure who guides the others through the darkness, and a villain who is somehow associated with or causing the darkness in the story.
Well, in such a novel, there could be a group of characters. For example, a young adventurer who is the central figure, and his or her friends or companions. One of them might be a strong - willed person who encourages the others when they are in the grips of the 'darkness'. Another could be a more timid character who gradually grows stronger throughout the story.
I don't have enough information to say who the main characters are in 'good dreams novel'. It could be a young protagonist on a quest related to their dreams.
I don't know as I haven't read the novel. It could be a young protagonist who is trying to make sense of their dreams.
Not having read the 'City of Dreams Novel', I can only speculate. There could be a hero - type character who is on a quest within the city. Maybe there is a female lead who is strong - willed and fights for equality in this city. And then there might be some side characters like a street - smart orphan who helps the main characters navigate the more dangerous parts of the city.
I'm not sure without reading the book, but usually in a novel titled like this, there could be a protagonist who is deeply connected to the 'House of Dreams'. Maybe it's someone who has a special vision for this place or is on a quest related to it.
It's possible that there is a character who has some special connection to the darkness. This character could be either a force for good, trying to understand and control the darkness, or be corrupted by it. And there could be other supporting characters that help or hinder this main character's journey in the novel.
Since I haven't read it, I can't say for sure. But it might have the Lord of Darkness as a main character. There could also be some characters who oppose him, like a brave knight or a powerful wizard.
