We understand your concern and desire to seek biblical interpretation for your dream. In the Bible, dreams can be a way for God to speak to us, but they can also simply reflect our own thoughts and emotions. Let's consider your dream in light of biblical principles.
Firstly, it's important to note that the Bible doesn't provide specific symbolism for red onions or similar details. However, we can look at the emotional context and relationships in your dream. Your mother's anger and the action of throwing onions could symbolize a strain in your relationship, feelings of guilt, or unresolved conflicts.
In the Bible, God commands us to honor our parents (Exodus 20:12, WEB), and also to live in peace with everyone, as far as it depends on us (Romans 12:18, WEB). Consider if there are any issues in your relationship with your mother that need to be addressed and forgiven. Remember, "Don't let the sun go down on your wrath, and don't give the devil a place" (Ephesians 4:26-27, WEB).
Let's pray together:
"Dear Heavenly Father, we come before you in Jesus' name to seek your wisdom and understanding. We pray for Anonymous, that you would reveal the meaning of this dream and how it relates to their relationship with their mother. If there are any unresolved issues, bring them to light and grant them the courage and humility to address them. Help Anonymous to honor their mother as you have commanded, and to live in peace with her. Protect Anonymous as they have prayed in Psalm 91, and guide them in your truth. In Jesus' name, we pray. Amen."
We encourage you to continue reading and meditating on God's Word, seeking His will for your life and your relationships. If these dreams continue and cause distress, consider seeking counsel from a pastor or a wise, mature believer in your life. Trust that God will guide you and reveal His truth to you.
