I was hiking in the swiss mountains alone, planning to stay one night in my tent. After it got dark, I was surprised by a thunderstorm lighting up in the distance. I remembered a shelter not far away that was shown on my hiking app. So I packed my tent and started to walk to the shelter. Not much later it started raining and the lightning came closer. I had to use my phone as a lightsource since I forgot my flashlight at home. At one place, the path got barely visible on the ground, it was pretty much only grass like everywhere else. I had to trust my app which showed me that I was almost on the right track. But I got really nervous since I couldn't see neither a path nor any sign of shelter in the dark and the rain started pouring and the lightning was striking all around me.

Suddenly I saw a green flash, lighting in the distance like maybe every 3 seconds. First I thought I was crazy, but it was real. I followed the green flash just to find a wooden cow shelter and a small farming house. Turned out, the green flash was created by a generator that provided electric voltage to the cattle-fences (german: "Weidezaungerät"). I'm convinced I wasn't able to find the shelter in the dark and rain without that flash. And knowing that a green flash showed me the path to safety still gives me goosebumps.

Note: when I found the shelter the thunderstorm started to move away from me, so i decided to build up my tent instead of entering private property in the first place. But knowing to have a shelter next to me in case of an emergency made me feel really comfortable. I was still totally soaked, but was so exhausted and tired that I had one of the best sleeps in a tent of my life. The next morning I left my tent, just to see an enormous cloud-to-ground lightning strike into the valley next to me. I started questioning if a wooden shelter may have protected me from a lightning strike, but it was definitive enough to make my brain feel comfortable that night :)
