Corn in a dream is a symbol of fertility. This can mean physical fertility, the ability to produce children, but it can also mean mental fertility, the ability to generate new ideas and to invent and design new things.
Corn can represent abundance, so if you dream about a field of corn, it can mean that you are feeling satisfied. However, it can also mean that you desire satisfaction.
A dream that you are harvesting or eating corn can mean that you are reaping the rewards of your efforts.
If you are making something out of corn, such as cornbread, in your dream, you want to put your inherent talents to practical use.
Corn in a dream can be a pun on the word “corny”.
