Got a few here,
When I was like 8 the ice cream man parked across the street from me, so I go over and buy one, then I started walking over to my house but my left side was blinded because of the truck and I walk out and an old lady flew right past me, another 1/2 inch and her car tire would have shattered my foot, possibly killed me.
Another time I was like around the same age, I was at the beach, and I went in the water, got pulled in I tried fighting the water, but just got pulled in more and more, eventually I hit the drop-off and I was drowning, but no one could see me because I was small, but fortunately for me there where ropes with those colored balls on them that it took me a while to grab onto, and I made my way back.
Another time was in the first grade when I passed out in the gym due to the flu.
