What does it mean to dream about hat?
A hat often points to a role you take on or an attitude you put on, so it helps to ask whose hat it was and whether it suited you.
Four ways to read it
Each reading below comes from a named tradition and a cited source, so you can see where it came from and decide what fits your dream.
Freud
Freud would read what covers the head as concealment of thought, and at times a symbol of rank or of the body. Putting on or losing a hat can carry a wish about how one is regarded.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might see a hat as the role or office you assume, the cap that marks a function. Which hat you wear can show which part of yourself is in charge.
Jungian concept (our summary).Modern
Continuity ties hats to waking thoughts about the jobs and roles you juggle, the many hats people speak of wearing. The hat in a dream often matches a part you are playing in waking life.
Continuity hypothesis (our summary).Mythological
The cap of office and the magic hat run through myth, from the helm of darkness that hid its wearer to the crowns and caps that marked king and trickster alike. Headgear has long signalled who holds power.
