So I discussed how the best ideas one can conceive naturally have to come from within oneself. It works the same way good dreams appeal specifically to the person dreaming them. To obtain one's absolute favorite story, or favorite song, one has to make it. A friend of mine had the rebuttal that the place that people get their ideas is from experiencing others' works. Which is true, though again, everyone is filtering all of this through their own "lens" of perception, and rearranging it as they see fit to make it best/most appealing to them.
(not all the time, but that's sort of what stories and music are, at least plenty of it. Rearranged things, ideas, melodies, that were heard before)
Drea-ea-ea-ea-eam, dream, dream, dream...
