It wasn't hunting, but once during a really tough 24 hour backcountry mountain bike race, I got caught in a lighting/hail storm on top of a mountain in the middle of the night. I didn't get struck by lightning, but I did get hypothermic. There were a couple of young guys truck camping at a nearby pass. I had talked to them earlier in the evening prior to the storm, and, in my hypothermic stupor, decided to get in the cab of one of the trucks to try and warm up.
I fell asleep briefly, then woke up. It was still pitch black dark, and I could see headlamps flickering about 200 yards away. I thought it was someone involved with the race I was in coming up to look for me. Then the lights went away and re-appeared several more times in the same spot before stopping completely. Once the sun started to come up, I talked to the truck guy (who'd been asleep in the back) and went on my way. Never thought much about the lights I'd seen after that.
One year later, I returned to the same spot to spectate the race. It was dark, and I was hiking the same ridge. I saw a headlamp ahead of me in the dark. I went around a rocky rise in the ridge, and on the other side (where I'd seen the light)... nothing. Cliff faces on both sides- there's nowhere else a human could have gone.
Ghosts, man.
