I have a few.
Aged 8 or 9 I'd been allowed to watch something on TV, it might have been a Stephen King story, but the episode ended with a child in mid air scratching the window from outside.
I was woken up by the sound of scratching on the window. I sat up in the dark and tried to think what to do, eventually I moved the curtain back - the cat had been locked out and manged to get to my window sil.
the second I was about 17, I'd been off VI form for a day with belly ache. My mum had gone for an afternoon nap as she often did and I tried to get out of the chair and found myself on all fours with right sided pain like I had never felt before.
I tried calling my mum but she didn't wake up.
Eventually she came down and I asked her to call the Dr. She told me to take paracetamol and go to bed. I said I can't get to bed I need a Dr.
My brother came home from work and went out and then my dad came home about 6.30ish.
It's the one time my dad has ever gone against my mum's wishes, he called the Dr.
The Dr came out, took a look at me and called an ambulance before examining me.
The ambulance crew arrived and made a couple of jokes about me looking green, I had jaundice.
To cut a long story short it was my gall bladder, but I thought I was going to die because my mum wouldn't call a Dr.
Third one.
I was in the outside lane of the M1, my accelerator cable snapped. I managed to get t the hard shoulder by sheer luck and tot he tune of several HGV's horns.
