Yes, in a dream. It saved my life and the lives of my four children.

Totally unrelated to the dream I was having - I heard my best friend calling my name and it woke me up. The gas heater had run low on gas and the fire had gone out but the remaining small amount of gas was pouring into the house. It smelled really bad and I ran to the heater and turned off the gas feed in tap! Scary stuff.
