A couple of years ago I was at my brother’s house when there was an explosion in the middle of the night that shook the windows. It was a few blocks over where a gas explosion turned a home literally (word used correctly) into toothpicks. An elderly woman lived there alone and survived. She had gone to bed and awoken in her backyard, wondering WTF. Apparently her mattress protected her somehow even as the wall of her bedroom was blown out and her with it. She was shaken but completely unharmed.
