Dreams featuring dolphins can symbolize a variety of meanings, often related to intuition, communication, and emotional depth. Let's break down your dream:

1. Two Dolphins: The presence of two dolphins may indicate a duality in your life or a relationship. Dolphins often represent joy and playfulness, suggesting that you may be experiencing or seeking more light-heartedness and connection in your waking life.
2. Grey Dolphin: The grey color can symbolize balance and neutrality. The fact that this dolphin allowed you to touch it on its first visit suggests that you might be feeling comfortable and open to exploring your emotions or new experiences. It may represent a sense of stability and trust in your life.
3. Yellow Dolphin: Yellow typically symbolizes happiness, optimism, and energy. However, the fact that this dolphin had red eyes could suggest that there might be underlying emotions or warning signs associated with this energy. The delay in its willingness to be touched until its third visit might indicate that you may need to be patient or put in more effort to connect with this aspect of your life or someone in your life.

Overall, this dream could reflect a journey of emotional exploration, where you are learning to communicate and connect with different aspects of yourself or your relationships. It may be encouraging you to embrace both the playful and serious sides of your emotions.

Consider what these colors and the dolphins’ behaviors mean to you personally. Reflect on any current situations in your life that might relate to feelings of trust, patience, or emotional exploration.
