You know, I'm not sure Deb.
This might sound wacky, but I honestly think the idea for my book (as one example) came from my "future self"--or part of myself that is in another dimension ("heaven", the "other side", whatever you want to call it).
I think zoning out helps us be receptive to inspiration because the conscious mind (or logic or super ego or "inner critic") isn't (yet) engaged to shoot down the idea.
Running with the idea is another story (putting scaffolding under those "castles in the air"), as is having the talent to support, create and launch the idea.
For example, someone can have an inspired idea, but if they don't have the ability to communicate it effectively in some way, then it might be "aborted". So this is where study, discipline and diligence come into play.
Does that make any sense?
