Yes. When I was thirteen, I rescued a little boy who had broken through the ice in winter. The adults nearby could not reach him, the ice was too thin to support their weight. One spotted me and asked me to try, because I wasn't as heavy as them. I stepped on the ice, broke in, stood waist deep in the icy water, grabbed him and pulled him out. Then I climbed back out, too. The story ended with the boy's mother not even thanking me, even though she and my mother knew each other .... And that I got severe pneumonia and was in bed for two weeks.
At least, one of my classmates sent me chocolate ... that was nice. XD
Have you ever dreamed something and later it actually happened in reality?
