I have a 20 year old daughter that since she was a baby she would see spirits. When she was 12 to the age of 18 she would wake up with scratches on her arms and legs and bruise marks on her arms in the shape of a hand. This was a different houses and brand new ones too so I know that nobody died in any of the houses.
We lived in northern California, just recently we moved to San Diego, CA 470 miles away and she still sees and hears spirits, even at other peoples houses. Right now 3:30 am she came to our room because a spirit woke her up, it just said her name close to her ear in a deep voice.
I tell her that she's a medium and that she should learn how to talk to them. Maybe they need help crossing over or sometimes they don't know they're dead.
Well my question is, is there any way to make this stop? I know it's not the house.

Does she want them to stop, or just you? Is she afraid of what is happening?

I'm a little confused by your telling her she's a medium and should pursue this, and then asking how to make it all stop.

Actually she is the one that wants it to stop. They haven't hurt her lately and it seems like she's gotten used to it but it still scares her when they haunt her. What I mean by that is when the spirits are scaring her on purpose like waking her up calling out her name.

New at this just noticed the reply button.

Either way (reply or answer) is fine.
I'd suggest that she ask here so that she can best describe and discuss what she wants. She may simply be someone who sleeps lightly enough that her dreams enter what she thinks is a fully awake state, and can make it stop by changing eating habits, having a night light, leaving a radio on low music, or any number of methods. Or she can visit a medium who can advise her how to take control of spirits and make them not scare her.

You're right, it's not the house, it is her. Is there a reason you haven't contacted a church about it?
