For normal people, it has a simple meaning: fertility, health, love (beautiful and good), lust and temptation. Dreaming of an apple also denotes one’s determination and good will.
For the ancient people, if someone had a dream with an apple, the dreamer would learn something important, since an apple was a fruit which contains the seeds of knowledge.
If you are a woman and wants to have children someday, this dream means that your children will be beautiful.
If you ate the apple in a dream, it means that your life will change for better. Prosperity and happiness are coming !
