Dream about wearing a big hat is sometimes your ideal self and your notions of perfection. You are expressing your anger in such a playful way that others do not recognize or acknowledge your true feelings. You are allowing others to control you. This dream is a premonition for emotional wholeness, continuity, commitments and honor. You are taking advantage of some situation.
Wearing a big hat dream is a sign for your emotions and your ability to control your emotional urges and energies. You may be questioning your identity and who you are. You are regretting something you have said. The dream signifies an aspect of yourself that is striving toward greater understanding of who you are and of the world you live in. Your subconscious is psychologically preparing you for a new role.
If you dreamt about wearing a big hat:
Your ideals will feel especially sensitive to you today. You may sympathize with others more than you normally do, but be careful that you don’t get caught up in the role of champion for others. That is a noble sentiment, but you need to stay focused on yourself right now, and this will take some committed effort. Go for a run with a friend and discuss issues that concern you. The increased oxygen intake will settle your mind.
