the key to understanding David Lynch's work is surprisingly simple. I was surprised.

David Lynch is a collage artist. He plans out his films by creating his storyboard literally as collage- magazine clippings, stills from other movies, etc.

He chooses stuff that emotionally speaks to him and builds a sequence out of powerful imagery that serendipitously creates a gestalt.

it doesn't fully make narrative sense because your linguistic centres is not what he's trying to talk to.
