Yes, We had a young girl living in the closet in my bedroom when I was a teen. She moved to the house next door when we were on a 2 week vacation. They had younger children and heard her on the baby monitor one evening.
Then I bought the house across the street. The husbands first wife had died and was in residence there when he was still living there. They have pictures with her in them. And there was an old man who lived there as well. He would go sit on the bed next to my 2 year old son and watch him sleeping. I had to tell him to go away and leave my son alone. He would wake him up and freak him out.
