Dream about wearing white hat is about your childhood and the corresponding feelings that you associated with the holiday. There is something that you need to come clean or confess to a person. Your high ideals are crashing down on you. This is a harbinger for feelings of vulnerability and hostility. Your subconscious is telling you not to repeat the same mistakes that you had made with a ex-boyfriend/girlfriend.
Wearing white hat dream is an evidence for your level of understanding, awareness or success. You need to reconsider the direction in your life and to rethink the path you are taking. You need to get something off your chest. This dream points at your personal responsibilities and sense of independence. You are feeling ineffective.
If you dreamt about wearing white hat:
You are going to have to limber up if you are seriously looking for love. It would help if you could do away with the usual and try something different. You need to update yourself with a fresh style and a new approach. You and another will love it.
