First in the bible it says God has promised His beloved sweet sleep in-Proverbs 3:24 when you lie down, you will not be afraid; when you lie down, your sleep will be sweet.
Proverbs 1:33 but whoever listens to me will live in safety and be at ease, without fear of harm."
Proverbs 6:22 When you walk, they will guide you; when you sleep, they will watch over you; when you awake, they will speak to you.
Jeremiah 31:26 At this I awoke and looked around. My sleep had been pleasant to me.
My daughter used to get really bad nightmares and I had to get stuff out of my house that was inviting the evil spirits in and I prayed and bound up night terror and witchcraft in Jesus name.
The bad dreams went away.
Also I am not sure what your dreams are about but God does give us dreams so we can pray over them and intercede in Jesus name.
What would I pray for on this?
I would pray in Jesus name I pray that you will give me sweet sleep as you promised, and I bind up and break the powers of night terror, all night attacks, and witchcraft in Jesus name.
I also ask for forgiveness is this has been invited in through any sin that I have committed in Jesus name. I plead the blood of Jesus over my house, property, over the door posts and lentil of my house in Jesus name.
Also I pray for understanding and knowledge of this in Jesus name.
I hope that you will pray over your sleep.
I do have pages on prayers, faith, and overcoming attacks by faith.
God bless you!
