I was falling off a cliff , lost my grip free climbing alone, fell backwards only had my toes on the rock. Past vertical, hands over my head when a hand slapped hard against the middle of my back and pushed me forcefully back up against the cliff wall and I managed to grab ahold of the rock face..
I was totally alone but I looked back and said, "thanks man" instinctively..
The person who saved me would have to have been directly behind me literally floating in the air to do what happened..
It was an eye opener that's for sure.
