Fatigue can also be related to the head injury. Irrespective of the dreaming.
I would talk to the doctor about this because it is significantly affecting her.
I would also recommend psychotherapy to help address the underlying issues and also as a way forward. It sounds like there is a lot of unprocessed material there.
A lot of trauma and a lot of life changes.
It might. I get dreams like those but not to the extent of being tired when I wake up. If you get really concerned, take her to the doctor's and see what they think. hope this helps
Yes, it very well could. Keep in mind that some of the dreams are family related. You need to find out if they are scary dreams and if so, you need to confront them. Ask her what she is dreaming about and have her talk about it. Also, I hope she is getting at least 8 hours of sleep each night. You should probably make it more. If the problem persists you might want to get her a CAT scan, or get her a MRI. Hope this helped :)
