Mourning before the fact of loss may denote a displacement to the current and conscious object of a sense of loss of a different and former object in the unconscious. The conscious preoccupation may act as a resistance in analysis. Rosner reports the case of a young man who brooded over a premonitory dream of his father's death which represented a defense against the fear of losing his mother—a recurrent theme from his childhood neurosis. The dream was overdetermined since it also represented a defense against repressed elements of the Oedipal conflict including fear of castration.
