The first association I have with your dream it's "The Princess and the Frog story or animation "
Tiana had a dream to start her own restaurant.......... Tiana and Naveen decide they are content to live together as frogs, and are wed by Mama Odie. Because of Tiana's new status as princess, their kiss restores them back to human form. The couple return to New Orleans to celebrate, and Tiana and Naveen buy and open the new restaurant.
So Tiana found a true love and realized her dream.
Probably your dream show that you will find your tiara ( Princess status) and will realize your dream through transformation( frog)
The frog is symbolic of:
Cleansing
Renewal, rebirth
Fertility, abundance
Transformation, metamorphosis
Life mysteries and ancient wisdom
Perhaps it indicates you need to “detoxify and take care of your health differently. Or it encourages you to release your emotions or carefully at how you spend your energy in relationship to others or some matters of concern in your life.
Cleansing might also mean that the frog spirit animal inspires you to renew your perspective or vision. If the frog shows up in your life as a spirit guide, it may encourage you to clear old opinions and beliefs to adopt a new stance or perspective.
The frog symbolizes the cycles of life, in particular the rebirth stage. Its own journey through life, from tadpole to the adult state, reminds us of the many cycles of transformation and rebirth in our lives.
