I agree that she needs to learn how to protect herself with white light and Angelic protection. She needs to give the Angels permission to protect her, they can only act on free will.
I also think that she needs to purify her house in some way, white light again is a good way. I've used a Wiccan house cleansing on my house, had a very similar situation where something was trying to enter me when asleep. I was too scared to sleep, getting around an hour before waking in a panic each night. The house cleansing worked extremely well. I found it on the internet. Google it, you will know when you find the one right for you.
