I have been in two serious car accidents when I was younger. The first I was driving bad from a local park at dusk after a long hiking trip. I hit black ice and the car did donuts and skidded down a ravine. I was unhurt somehow? and scrambled back up the cliff to the road. I was in the middle of a very deserted park just before dark, miles from town. At exactly the moment I climbed up the bank, my best friends mother and sister drove up. They were out having a mother daughter drive/talk. If I hadn't come onto the road at exactly that time, they would have driven by not seeing me or the car. I asked why they were out there, and they didn't know why they drove out that way.
The second unexplained experience was another car accident. I was broadsided while delivering pizza. The truck hit my car going fast enough to move the engine TWO feet to the right. My car spun around and somehow the door behind me was punched in a foot or so. I became the center of gravity as the car spun around a few times. When it stopped, someone opened the door and looked in horror as I had a HUGE s eating grin. I didn't hit my head, bite my lip or have a sore back or anything. The only weird effect of this accident was the end of a reoccuring dream/nightmare. For some reason the dream I had since childhood left me and I have never had it again.
Why I was spared injury ill never know for sure. I have a belief in spirit guides, but its more of a belief born of explanation than faith or religious upbringing. Why how who?
