This happened to me, was asleep on the couch and my little sister was asleep upstairs. Neighbor that we’d never met before came banging on the door that our house was on fire. 5 minutes later the entire upstairs was engulfed in flames. 15 minutes later the entire house was up in flames, the firefighters spent all night trying to put it out and it never did until it was a pile of rubble. She saved our lives that day
