Depending on the context of the dream, a hat can have a variety of meanings. Dreaming of a hat could indicate that you are hiding something or covering up some aspect of your personality. (As in wearing a hat to conceal a bad hair day.) A hat could also represent one or more of the many roles you play throughout the day/week/your lifetime. Depending on the type of hat you are wearing it could represent one or more of these roles. Examine the hat and the condition of the hat for more clues as to which of your roles is portrayed in the dream. If the hat is in good condition it indicates that you are confident at performing that role. If the hat is in poor condition it indicates that you lack confidence in your ability to perform that particular role. Alternatively, dreaming of a hat could indicate a desire for warmth or to be kept warm.
