The flood I went through, lifted cars, lifted graves out of the ground, pulled up the sewage into flood waters, it was the most disgusting thing I've ever been in. Neck deep waters with snakes, and shit all over, and old corpses floating everywhere. Doors and windows had to stay open because of the humidity and overall toxic environment, also the pressure of the waters causing damage. We were stuck there surviving on the top floor. Took days for the water to recede. It was horrible. Their wording is probably just to get attention but yes things can and will float through homes in a dangerous flood.
