When you get an idea, so many things come in that one moment. You could write the sound of that idea, or the sound of the room it's in. You could write the clothes the character is wearing, what they're saying, how they move, what they look like. Instead of making up, you're actually catching an idea, for a story, characters, place, and mood - all the stuff that comes.
David LynchYou've got to let accidents and strange things happen - let it work, so it's got an organic sort of quality ... By trying to remove yourself you can see some fantastic things sometimes.
