A hat in a dream is a not too common dream symbol however the way it is used in your dream could be very suggestive in terms of its overall significance. If it is taken from you there may be a pending confrontation with someone in your day to day life. If it is put on you, there may be the suggestion of the acquisition of more power to you in the very near future. If you are putting one on yourself, or find yourself wearing one in an unfamiliar situation in your dream, you could be covering your head as a sign of disguise or a need to blend in with a crowd in your current situation. If you are giving the hat to someone else, you may be thinking of making a romantic overture or invitation in the very near future.
