We understand your concern for your parents' health and the distress caused by bad dreams. Let us come together in prayer and seek God's will for their lives.
Firstly, we should remember that God is the ultimate source of life and health. As it is written in Psalm 68:19-20 (WEB), "Blessed be the Lord, who daily bears our burdens, even the God who is our salvation. God is to us a God of deliverance. To God the Lord belong the ways of escape from death."
Let us pray:
"Dear Heavenly Father, we come before You in the name of Jesus, lifting up our beloved parent's health. We ask for Your divine protection and healing power to be upon them. Grant them long life and good health, according to Your will. In Jesus' name, we cancel all the power of bad dreams and declare peace and blessing over their lives. Amen."
Regarding bad dreams, we should remember that God has not given us a spirit of fear, but of power, love, and self-control (2 Timothy 1:7, WEB). Bad dreams can be a result of fear, stress, or even spiritual attacks. It's important to fill your mind with God's truth and not dwell on fearful thoughts. As Philippians 4:8 (WEB) says, "Finally, brothers, whatever things are true, whatever things are honorable, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report; if there is any virtue, and if there is any praise, think about these things."
Lastly, we commend you for ending your request in Jesus' name. It is only through Him that we have access to God, as it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'"
Keep trusting in God and praying for your parents. We will join you in praying for their well-being and for your peace of mind.
