Freud y cine

"ideas are like fish. If you want to catch little fish, you can stay in the shallow water. But if you want to catch the big fish, you've got to go deeper" David Lynch

Before starting analizing Freud's theory in David Lynch's movies I would like to comment on the results obtained in the survey made by the film critic Jose Andres Solorzano at the Iberoamerican University in Mexico City. Thestudents could only answer yes/no to questions after watching a scene of David Lynch's Blue Velvet. The questions where "Did you like the scene you just watched?", "Would you watch the entire movie?", "Would you consider this scene perverted?", "Do you consider youself as a pervert?", and "Do you know what perversions are?".
This was the first time the students watched this scene, without previousknowdeledge on Lynchean movies. 28 students out of 30 said that they liked the scene and everyone said that they would watch the entire film. "This I found surprising, because no one has felt repulsed by the rape and the violence caused to Dorothy" the critic writes in his analysis. But the most surprising fact is that just half of the student knew what the perversions are.

From a cientificperspective we can say that sexual impulses in humans are instinctive, they are the biological need to transmit genetic material. Livido can have different ways of representations in human beeings. 
Freud also believed that the libido developed in individuals by changing its object, a process codified by the concept of sublimation. He argued that humans are born "polymorphously perverse", meaning thatany number of objects could be a source of pleasure. He further argued that, as humans develop, they become fixated on different and specific objects through their stages of development—first in the oral stage (exemplified by an infant's pleasure in nursing), then in the anal stage (exemplified by a toddler's pleasure in evacuating his or her bowels), then in the phallic stage.
 According toFreud, the instincts are linked to needs that have to be satisfied, because they are the basic principle in pleasure. Fixations are found when an instinct is closely related with the object that gives satisfaction. "Perversions are fixations linked to erogenous zones, we find example of this in perversions such as Voyeurism that makes the eye as the erogenous zone" Freud on Beyond the PleasurePrinciple. Sexual perversions can be defined as well as such activities that excludes coitus. One example of this is David Lynch's Blue Velvet. There is one scene where the characters Dorothy and Frank have a sexual encounter without coitus, that leads to Frank's orgasm.
 Even though perversions are categorised in different ways, im going to classify them in my criteria based on Lynch's movies.Inversion- This is the most famous perversion known mostly as homosexuality or bisexuality. Freud classifies it in three different types, the 
absolute inverted, which find the sexual object in people of the same sex, hermaphrodism and occasional inverted. We find an example of this in Mulholland Drive. The first sign of we get is Rita and Betty's first date when they attend Silent Club, this couldbe an occasional inversion. The second sign is when during the second part of the film Diane and Camille Rhodes have relations; at first we could guess it could be occasional but then in the scene where they announce Camillas and the director's engagement, we can realize that she actually is rejected by him, which suggest that she could be an "absolute inverted".
Fetishism- is the substitution ofthe normal sexual object for a related new object, but inadequate to perform normal intercourse with. This objects can be almost everything, they could  be parts of the body or objects related to the person such as lingerie, shoes, etc.
In Blue Velvet, we can see the relationship Frank has with the scrap of Dorothy's blue velvet robe, and how he asks her to wear the robe for his excitement. The...
