My girlfriend has been haunted her whole life by apparitions and shadow people being in her house, I really care for her and I would do anything to have her sleep in peace every night. What can I do?

Hello friend,
I'm sorry for you.
Firstly you have to go to the root cause of her problems. You say her whole life? Is it because of something she did or something done by the family.
I am not being able to pin point your entity. Is it like a demon or a spirit. Is it aggressive? If you could elaborate i could try to help.
