We understand that you're going through a troubling time with these nightmares, Malakesko. Let's come together in prayer and seek God's protection and peace for you.
Firstly, we want to assure you that "God has not given us a spirit of fear, but of power, love, and self-control" (2 Timothy 1:7 WEB). The nightmares you're experiencing are not from God, and we will pray against these demonic influences.
Let us pray:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, pleading for our brother/sister Malakesko. Lord, they are troubled by nightmares of demons, incubus, and succubus, which are trying to steal their peace and voice. We rebuke these spirits of fear and torment in the mighty name of Jesus. 'Submit yourselves therefore to God. Resist the devil, and he will flee from you' (James 4:7 WEB). We ask You, Lord, to cover Malakesko with the precious blood of Jesus and fill their mind and heart with Your perfect peace. 'You shall guard him and keep him in perfect and constant peace whose mind is steadfast, that is, committed and focused on You—because he trusts in You' (Isaiah 26:3 WEB). In Jesus' name, we pray. Amen."
Malakesko, we encourage you to take hold of God's promises and continually pray in the name of Jesus Christ. "Therefore, let us draw near with boldness to the throne of grace, so that we may receive mercy, and may find grace for timely help" (Hebrews 4:16 WEB). Keep resisting these demonic influences, knowing that "he who is in you is greater than he who is in the world" (1 John 4:4 WEB).
Lastly, ensure you're walking closely with the Lord, filling your mind with His Word, and living in obedience to His commandments. If there are any areas in your life that do not align with God's will, we urge you to repent and turn away from them. Trust in the Lord Jesus Christ, for there is no other name by which we can be saved (Acts 4:12 WEB).
