Freudian Perspectives: Prior to Freud's development of psychoanalysis, even sophisticated psychologies tended to associate the realm of the undead with premodern demonological mythologies. Freudian thought legitimized the human fantasies of the undead as a topic for serious scientific research. Freud developed a modern map of the unconscious, which he saw as a repository of denied desires, impulses, and wishes of a sexual and sometimes destructively aggressive nature. In sleep we view the unconscious as a landscape inhabited by those aspects of life that go on living, the realm of the undead spoken through dreams.
According to Freudian psychoanalysis, vampire narratives express in complex form the fascination-both natural and unnatural-which the living take in death and the dead. From Freud's point of view, "All human experiences of morbid dread signify the presence of repressed sexual and aggressive wishes, and in vampirism we see these repressed wishes becoming plainly visible." Freudians emphasize the ways in which ambivalence permeates vampire stories. Death wishes coexist with the longing for immortality. Greed and sadistic aggression coexist with a compulsively possessive expression of desire. Images of deep and shared guilt coexist with those of virginal innocence and vulnerability.
Freud and his early followers were right in their assumption that the vampire myth was grounded in archaic images of repressed longings and fears.
