Not me, but my mom before I was born. She was riding in a convertible with a friend of hers. They came to an intersection and the friend wasn’t paying attention and lost control of the vehicle. There was a big rig going through the intersection and they went right under the trailer. My mom ducked, the driver didn’t not. Driver was decapitated, my mom was lucky and only ended up with a scalp full of glass and some serious psychological trauma. She had to get over 200 stitches in her scalp But nothing else significant.
I think about it all the time and think how close I came to never being born at all.
