David Foster Wallace makes another brilliant observation about Lynch's films that is worth consideration. He writes: "This is one of the unsettling things about a Lynch movie: You don't feel like you're entering into any of the standard unspoken and/or unconscious contracts you normally enter into with other kinds of movies. This is unsettling because in the absence of such an unconscious contract we lose some of the psychic protections we normally (and necessarily) bring to bear on a medium as powerful as film. That is, if we know on some level what a movie wants from us, we can erect certain internal defenses that let us choose how much of ourselves we give away to it. The absence of point or recognizable agenda in Lynch's films, though, strips these subliminal defenses and lets Lynch get inside your head in a way movies normally don't. This is why his best films' effects are often so emotional and nightmarish. (We're defenseless in our dreams too.)"
