Twice when I was a child.
One time I was crossing the street in front of our house and there was a truck, since I was small he didn't see me. If my cousin hadn't screamed at him to stop he would've crushed me

The other time I was at the beach, I kept jumping to get my head out of the water but I was drowning and did not realise I was in an actual sea swirl until this lady swopped in and took me out the water to my crying mom on the beach.
