When I was a kid, about 4 or 5 years old, and still live in a village, playing alone and suddenly encountered a snake. My distance was pretty close with the snake and it moved really fast to my direction but I successfully run away. It was not a big snake but still it really scared me.
The other one, when I was still in elementary school, my brother forcefully pull me to the middle of a deep pool and then leave me there, not sure why he did it. Almost drowned but I'm able to save myself, but I drank so much water.
