I don't remember how old we were, but my younger brother and I were young enough not to be allowed to stay home alone overnight, so we were staying with my grandparents in their rather forbidding 1920s house.
Does anyone remember Nationwide, an early evening magazine TV programme? We enjoyed watching it because there were often funny bits, and we were allowed to see it that night at Nanna and Grandad's.
One of the items was a story about a bowl which was supposed to be cursed. I can't remember the details of the story but the idea was that the person who owned it would see a terrifying creature roaming the house at night.
Hours later, when I was lying in the big old fashioned bed in the big old fashioned house with my little brother in a room on the other side of the house with my grandparents, it came into my room.
I did not sleep that night, lying rigid in bed, eyes wide open. I've never been so terrified before or since.
About 10 years ago I think, the BBC website had a little regular 'stories from the archives' thing, and I was scrolling through it - and a story caught my eye. It was that bloody bowl creature, and immediately I was chucked straight back to that night, being a petrified little girl who believed it was in her room.
It was of course all in my imagination, but I can still see its outline on the flower patterned wallpaper.
