The instinctive jumping over some incomprehensible phenomenon, in the moment, also worked unbelievably well, the one time I did it.

I'd just applied a spray-on anti-slip floor treatment to the very-very-tiny bathroom floor, in a dodgy student apartment (mainly to cover up some ugly stained Linoleum). Then I see this tide of a thin layer of flame rolling rapidly at me, along the floor from the adjacent kitchen. Without thinking, I somehow jumped seemingly backwards, onto the edge of the bathtub, somehow didn't fall, and then jumped forwards, over the tide of flame, and out of the bathroom with the flaming floor treatment. Afterwards, I mentioned that I'd had the thought "fire shouldn't be coming from that direction", and I suspect that I was already jumping before that thought registered.

After the automatic, cat-like jumping, which I didn't know I had in me, I then consciously focused on grabbing kitchen fire extinguisher, and putting out the flames.

(Turns out that a gas from the floor treatment was highly flammable, and apparently heavier than air. Gas had rolled out, into the kitchen, and got to the pilot light beneath the apartment's mini oven/range.)
