Negative:
Rice is typically low costing and doesn’t have complete nutrition in itself, so seeing rice on its own can represent something that is cheap or incomplete. To dream about eating rice by itself can mean you are taking in teaching that isn’t fully nourishing you.
Wisdom:
Consider the context. If you are eating rice, or see it on a plate, it may represent spiritual nourishment. If you see yourself cooking rice, it could say something about what you are teaching to others. If you see rice growing in a field, it can represent growth or fertility. If you see it being stored up in abundance, it could represent a secure and stable supply. If you see it being hoarded, it could represent greed. If you see a single grain, it could represent dying to yourself.
Always go to God in prayer and ask Him to open the eyes and ears of your understanding to see and hear what He is saying and then make the necessary adjustments in your life that will bring about the desired changed in your character and in your life so you can gain the victory God desires you to have as you receive His message through His divine language of dreams.
