I don’t know if you would call this paranormal, or supernatural, or guardian angels, but:
About 6 years ago, some friends of ours went on a camping trip.
As they headed out of town, a truck swerved into their lane. As they tried to dodge him, their rig,(Suburban pulling a camper, pulling an ATV trailer), was caught in a huge wind gust. They had a nasty roll over.
One of their teen-age sons had not been buckled. He was ejected out of the side window.
As he hit the ground, somehow still staying conscious, he had shooting pain all over his body. By the time his mind was clearing up, a random car had stopped. The sweet woman who got out, claiming to be a certified nurse, began attending him until the helicopter arrived to airlift him to a bigger city.
On arrival of the helicopter/paramedics, when he was all situated, the family turned to thank her. She, her son, and the SUV she was driving, had vanished. No one saw her leave.
The boy went on to a long, difficult recovery, but is fully well now. I don’t think he would have survived if that angle hadn’t said a prayer over him that afternoon.
