Since I haven't read the novel, I would say the general purpose of telling dreams is to share your vision or special event that happened in your imagination. The ability to remember dreams is really good, because most people will forget. While you can tell dreams, try see if you can still visualise the dream. Some dreams can be in black and white, and some can be in colour. Dreams have no limit, they take you to your own little world.
Considering you haven't given the actual excerpts, some help would be that direct characterization is as simple as saying "The man is wearing a broad-brimmed hat". It is literally "direct", straight to the point. Hope this helps.
