When you see a dolphin in your dream, it's indicative of spiritual guidance, intelligence and trust.
Dreams about dolphins are generally inspirational so if you felt positive in the dream- perhaps you are in a good place right now. This positivity might enable you to move forward with something in life, either personally or professionally.
It can also mean that you've become more self-aware lately. Perhaps you have a greater willingness to look further into aspects of your personality. Consequently- you have a better understanding of who you are and what you want in your waking life.
Dolphins are often associated with an exploration of emotions so if you've been delving a little deeper into your own thoughts and feelings lately, this might be why they appeared in your dream.
One final thought process is- with such newfound emotional awareness- you will have more freedom to explore the extent of your intelligence but in a more playful way than you have in the past.
