Awww I am so sorry to hear this and I will pray for her! One thing I learned years ago is that if we are sleeping too warm or too hot, our bodies / minds can produce nightmares in order to wake us up to cool our body down(pull off covers etc). Not sure if that could be helpful but that popped in my mind when I read that and figured I should share. God Bless you both 🙏🏼❤️✝️❤️🙏🏼
