I grew up in my Grandparents house which was haunted and previously owned by a priest.
My Gramps would get tapped on the shoulder, feel breathing on his neck at night even though my Nan would be facing the other way.
All of their children saw stuff growing up, somebody sat in the rocking chair then the chair rocking randomly with nobody about.
As a child I would feel somebody sitting on the end of my bed at night etc, a certain picture of my cousin and I on the wall would never stay there, would always be on the floor the next morning, upright leaning against the wall but any other picture out there would stay.
None of my friends really believed it until my friend stayed after a night out when we were 18, we had both just gone to sleep when my chest of drawers were shaking so bad the drawers were banging in and out of them. She refused to ever stay again.
My DH (was boyfriend at the time) and woke up one night and said "(my name) are you okay?" I was fast asleep but it woke me, I said "yeah why do you ask? I was asleep" and he jumped out of bed and turned the light on as he had woken up to see a girl with long brown hair (same as me) stood in the corner of the room and thought it was me until he realised I was laying in bed next to him.
My Nan and Grandad were used to it and it just became the normal after 30+ years of living there. My Grandad passed away and I'd moved out, my Nan called me at 1am saying she was watching TV in the living room and could hear somebody stomping up and down the hallway and the bedroom doors opening and slamming she was petrified, I went to pick her up and she was so scared that she sold the house which broke her heart as they had so many memories there and had turned it from a 2 bedroom bungalow to a 5 bedroom, raised their children there and grandchildren etc.
Now my Nan has passed away too and I often drive past it and wonder if the owners now experience what we all did.
