Dreams involving birds often symbolize freedom, perspective, and communication. The presence of three red cockatoos in your dream could represent a few different themes:

1. Freedom and Expression: Birds are commonly associated with the idea of freedom and the ability to rise above challenges. The cockatoos, in particular, are known for their vibrant colors and social nature, suggesting that you might be seeking more freedom in your life or are expressing your true self.
2. Communication and Relationships: Cockatoos are social birds, so their appearance may indicate a need for better communication or stronger relationships with those around you. The number three could symbolize collaboration or teamwork, perhaps pointing to a need to connect with others.
3. Creativity and Passion: The red color is often associated with passion, energy, and excitement. Seeing three red cockatoos may suggest that you are being encouraged to embrace your creativity or pursue a passion that brings you joy.

Consider reflecting on your current life situation. Are there areas where you feel restricted? Are you looking to connect more deeply with others? This dream may be urging you to explore these themes.
