Most of the artists I respect seem to say the same thing, (over-simply) that it springs from a mysterious antenna in their mind (heart) that picks up things from (unconcious) sourses and turns them into something personal. Why people like this get ideas is something of a mystery; "where did that come from?" is often heard from such individuals, but they often don't question it, instead just allow themselves to be carried along by it to its creative conclusion. (self)Examination usually comes after.
Bowie, Goya and others I respect often talk like this...
Perhaps I'll post a question like that ...
