There are several view points on the subject, but they all seem to have a common theme: Frogs in your dreams mean blessings, love, and prosperity. (Yay, us!)
If you hold the frog in your dream which, by the way, isn't good to do in real life, it suggests that your fondest wish will come true. Frogs in dreams can also signify emotion or spiritual transformation; and if the frog croaks, it's a call to delve deeper into spiritual matters. If you see the frog in water, it can mean that you have turmoil in your life but you have the ability to see your way out of it.
When frogs jump into your life, its a sign that now would be a good time to jump into new opportunities, or to transition your life. Since we frogs go through some serious growing pains to reach adulthood, we make great totems for teenage humans who often have their own struggles...finding their own place between childhood and adulthood.
Whether or not any of this is true, it's kind of fun to think about. Animals, of all kinds, come into our lives for many different reasons. Whatever animals you have, dream about, or you come across in your daily life, please just remember to treat us with kindness and respect. We're here to share the planet with you and we serve a purpose in the Universe, just as you do.
I hope your that dream tonight include frogs. But whatever you dream about, may it bring you peace and, perhaps, a little more love.
