To dream of anything to do with acorns or the trees which bears them portrays you will be magnanimously lucky as success, prosperity and good fortunes shall eventually be your portion.
Acorns are great symbols to dream about because they represent your strength and your ability to grow on your own. In fact in the Nordic and Celtic mythology it represents fertility and immortality. The god Thor’s Life Tree was an oak and the word Druid can be translated as “Oak Knowledge”; see tree dreams.
