When I was a tiny baby my parents lived in an old conversion with an unusual layout and one bedroom off of the kitchen. My brother was almost two at the time and had that room since I was born to make room for me in the main bedroom, and over the course of a few weeks kept coming out with random facts about planets and animals and mathematical equations. (Not particularly understanding what he was saying, but very unusual things to say.)
He was going to a childminder for two afternoons a week (as I was a nightmare baby, my poor mum!) and one day the childminder came to see my mum to tell her my brother could read the paper, and she was really impressed.
My mum and dad said that she must be mistaken, so she took the paper out and he read an entire article, every word. (I swear! This story is much told in family by all concerned.)
My dad asked him, 'how can you do that' or something, and he said...
'The man in the fireplace teaches me.'
We had no fireplace, at all. So they asked him what man, what fireplace.
He said 'The man in the fireplace in my room.'
Within the next few months, my brother learnt to read everything, could do maths, etc. It was remarkable.
My Aunt was over for the day (every Thursday) and my brother was playing in his room and started absolutely screaming.
He told my aunt and my mum that the man in the fireplace wouldn't leave him alone and was nasty.
My aunt asked him where the man was and my brother pointed to his wardrobe.
My mum and aunt opened the fitted wardrobe and between them pulled the back panel off and found an old boarded up fireplace. Seriously. There's no way he could have known it was there.
He became so upset after this about 'the man in the fireplace' that my parents took him to the doctor, and eventually had to move house.
My brother is 32 now and is a genius. Full scholarship to Emmanuel School, first class degree. Amazing jobs.
But absolutely hates being alone. Won't watch scary films. Suffers insomnia and nightmares. And I know he was young, but he says he remembers it, but can't talk about it.
I swear to god that's all completely true.
