Can an analyst understand which structure you belong to based on a single dream?

I’m wondering whether, in the preliminary interviews needed to understand a patient’s structure, even a single dream might be enough to reveal it. Let me give a simple example: dreaming that a new Pope is elected and immediately killed. In Italian, the signifier papa echoes papà (father), and it would seem like a dream related to the Oedipus complex—something that would suggest repression and a neurotic rather than psychotic structure. Or, on the contrary—who knows—it could represent the foreclosure of the Name-of-the-Father.
So I’m wondering whether, in fact, a single dream could be enough for an analyst to place the analysand in one structure or another.
