However I believe it is an interesting thing to explore, and possibly understand how your mind works and thinks. You could strike up philosophical conversations with yourself and you might get amazing ideas.

It's entitled Lucidly Conversing with Dream Figures, with Robert Waggoner

His book covers a lot of stuff you mention here, especially about what's behind the dream itself and hidden information.
