I have a creepy story. Well, it was creepy to me and when I would tell it to people IRL, they were creeped out. I don't know if it will translate well as a written story.
My mom died in 1995. A year after she died, my dad started seeing my mom's friend, she lived across the street. She was a 50 year old woman who lived with her parents who whole life, she never had a BF. We were all for it! It started out with them just having coffee together. My dad went to us and explained he wanted to see her. I guess he was getting our permission? We told him mom was not coming back, and he was still alive, to go and have a life. Little did we know, that she was psycho!!! They dated and eventually got married in 1999. Very turbulent relationship. They fought constantly. She was very controlling and extremely jealous to let dad out of her sight.
My dad died unexpectedly in 2004. His wife did not take his death very well. She would tell us he was haunting her. We shrugged it off and chocked it up to her craziness. I would get together with my sisters and we would actually laugh about it.
About 8 months after my dad died, I had a dream. I dreamt that I was in my childhood best friends house, the one next door. When I was a kid and would sleep over, her upstairs bedroom window faced out to my house and we could see into my kitchen. In the summer with the windows open we could hear. Houses were close together. In my dream, I was in Kathy's bedroom, and I heard commotion in my dad's kitchen. In my dream it was present day. I was an adult, and my dad was dead. What I saw, was my dad in the kitchen, literally screaming in his wife face 2 inches from her. I ran over there and tried to pull him away from her, confused as to why I was seeing my dad in his kitchen. I turned around and my mom was standing there. She looked at me and said " She told you he was haunting her."
I woke up, and decide that her perception was true. My dad was messing with her.
I would definitely come back to haunt DH & DS, if they allowed that to happen.
