My main "haunting" occurred in a flat I lived in with my now ExH and my son who was aged between say 4 and 15. By bizarre happenstance too convoluted to go into we lived there twice, with a gap of maybe three years in between after a brief sojourn "oop North".
This flat was over a shop in a Victorian shopping arcade and was over two floors with the two bedrooms and a bathroom big enough to have been a bedroom in spacious attic style . When we first moved in we were somewhat disconcerted that the bathroom had a bolt on the outside of the door, bit never found out why.
That flat was so haunted we all had weird experiences, together and independently, and visitors often commented on feeling uneasy.
One night, during our first tenancy, DH and I were awoken in the wee small hours by a commotion in the loft space above us. We had sloping ceilings hence my reference to "attic" space but above that was the pointy roof with space underneath if you understand what I mean.
It sounded like furniture being dragged, footsteps, just an awful lot of noise. Now our bedroom was at the back, overlooking the alley three floors down behind the shops. My DS was next door at the front and his window looked out onto the curved glass roof of the Arcade. There was a small gulley that would have provided escape in a fire but at some risk lol.
His room was accessed down a very short narrow passage, and the trap door to the loft was in the ceiling directly outside his room. He would have been 3 or 4 at the time.
Now, the Arcade was down the middle of a big sort of oval arrangement of shops with flats above and is the sort of island in a gentrified shopping area. Difficult to explain but anyhoo. As a child I'd lived in a flat on the outside of the oval very similar in layout, and I knew that the lofts were all interconnected by gaps either side if the chimney breasts in the loft.
Therefore, I assumed it was the same in the Arcade, so it sounded as though someone had made their way along from another flat and was in our loft. I absolutely panicked, shot into my sons room and grabbed him out of bed because if someone was going to come down through the loft hatch they would be between him and us.
Meanwhile my burly biker DH rang 999 and the police arrived in due course with a dog unit as there had been a fair bit of petty crime in the area.
Very nice policeman went up the lift ladder with his torch and baton. The sounds had subsided by then but he did hear a bit so understood our concern and agreed with our logic.
The lift, predictably was empty and now silent. He looked at the area where I thought people might be able to come through and reported that unlike the other flats I described, there was no way of getting through, and likely never had been judging by the age of the brickwork at both ends of the loft.
After a bit of awkward discussion he surmised rats or squirrels but as this had only happened once in a few years of living there, we had doubts. Anyway, better safe than sorry....
Fast forward to when we finally moved out after our second tenancy. The flat was upgraded and rented out to young professionals. In between, the landlady's brother and teenage daughter, who I knew had lived there and reported some oddness. I was then told that on the first night one of the new young girls had taken up residence in our old back bedroom, she'd been woken by so much noise in the loft - bangs, crashes and dragging noises - that she bailed out that night, never went back, and sent for her belongings the next day.
There's more. Quite alot more. I'll add things as I remember them.....
