You down with MeDD

So. I've decided I need a Mental Dictation Device.

The way I write is pretty straightforward. I have the kernel of an idea. I begin to think about the idea, and where it could go. This daydream state is just as important as the actual writing portion.

As I grow obsessed with the idea, I begin to write it in my head. I narrate it exactly as I would narrate it on a piece of paper, only because it's my mind, I jump ahead to other sections and combine some daydreaming with it.

Then I begin to actually write it physically. At this point, whenever I am not at the computer actively writing it, I am narrating large sections. Like, when I'm in the bathtub, or in bed, or driving, or at work. I start at the beginning of a scene, and I simply start mentally writing the text. The words appear exactly as they would for the page. If any of it is particularly interesting, I make a note of it somewhere.

( Blah blah blah writing, short, I promise )

I'd just have to remember to turn it off when I start daydreaming about my Mary Sue characters. lol.

How about you? Any thoughts on writing processes? Would you welcome or curse a MeDD?
