Dreaming of swimming in the ocean often symbolizes exploration of your emotions and subconscious. Water typically represents feelings, and the ocean can signify the vastness of your emotional state or the mysteries of your inner self.

The presence of the humpback whale is particularly significant. Whales are often seen as symbols of deep emotional connections, intuition, and communication. The fact that you felt a strong connection to the older female whale suggests that you may be seeking wisdom or guidance in your life. This connection could represent a nurturing aspect of your personality or a desire for deeper understanding and insight.

Feeling peaceful in the dream indicates that you are in a good emotional space or are coming to terms with certain feelings. The herd of whales symbolizes community and support, so this dream may suggest that you have a strong support system or that you are surrounded by people who care for you.

Overall, this dream could be encouraging you to embrace your emotions, seek wisdom from those who have more experience, and recognize the beauty of connections in your life. Consider reflecting on your current relationships and any guidance you may be seeking.
