His movies are not supposed to be "got" completely. They are surrealist. They have the logic of dreams. Or nightmares. There are things in them that won't ever make literal sense.

Any film school graduate can string together some random images and call it "surreal", and mostly those would be boring. but Lynch was a master: in his films, all too often, just as your conscious mind was going "wait, what?" some subconscious voice would be nodding "yes, that fits".
