In dreams, hats have been said to represent “opinions, beliefs, mental attitudes.” (Crisp, 1990) They have also been said to represent “an extension of power and influence in the dream.” (Lohff, 1998)
When I was in graduate school at UC Davis, I had a rhetoric professor who would gesture to a phantom hat upon his head. This was his method of representing a given perspective. He would say: “If I were to think about this problem with my Foucault hat on, then I would say… But if I am to think about this problem with my Derrida has on, then I will say…”
If I have a hat in my dream, I contemplate my perspectives, beliefs, and attitudes. I ask myself: “Am I trying on a new hat? Am I entertaining a new perspective or attitude?” These questions seem to get my creative imagination flowing in relationship to the dream content.
