Great thread, time to get it kickstarted again. I've got a few decent ones and some shorter crappier ones. I'll write out the former category on their own first and I'll probably condense the latter category down into one.
First one:
My buddy and I were out one early Fall night in Maumee State Forest hunting for coyotes or a raccoon if we chanced on one. It started off as a fun night, spotted a couple possums by their eye shine right in the first 25 yards of the trail. We let the little buggers carry on with their business. Any critter that eats as many ticks as a possum does is a friend of mine.
As the night progressed, we would occasionally play raccoon or distressed rabbit noises off my friends phone (sounded terrible, about 0% chance anything would come into it). The moon was bright and full, so when the canopy was thin we would travel with no headlamps. The deepest portion of this particular section of state land was one such spot. In fact it was a totally clear cut rectangle, about 100x250 yards, with an old horse trail skirting the perimeter on 2 of the edges. The far edge of the clearing from where we entered was bordered by more woods for 300 yards or so, before the giving way to a soybean field.
Shortly after rounding the corner to walk that far edge, we spotted a dim orange light way off in the field, floating at about human height. Its weird to say, but my first thought was it was an old school lantern. We stopped to watch as we thought it might be a person heading our way. The light was moving up and down and side to side, almost like somebody looking for something in the dark. But try as we might, we couldn't spot a person anywhere near it, and certainly not holding it. We watched for several minutes and the light just seemed to keep meandering over the same little spot in the field, never really traveling. Since then I've always thought of the light as a will-o-the-wisp.
The light creeped us out, but eventually we got up and started walking again, albeit a lot more quietly. We hadn't made it 10 yards when we heard a nasty, raucous sound like animals fighting fire up across the clear cut. We were both initially excited, we thought it had to be a big 'ol boar coon. Excitement turned to doubt when we saw an entire, 30ft pine tree shaking at the location of the sound. Doubt turned to abject fear when the shaking transferred from the first tree to the adjacent one and on to the next one, impossibly fast. As soon as one tree would start up, the previous would stop, all the while the coon-ish noise would emanate from whatever tree was shaking. The wave of shaking, screaming trees traveled in a loop all the way around the outside of the clearcut. It must have been moving an easy 60 miles per hour, faster than any animal in the woods of Northwest Ohio could possibly move.
After making the loop, the noise and the shaking stopped all at once. All that was left was two, relatively in shape, 20 year old men with fully loaded AR15s sitting on the forest floor back to back quaking in their boots. We probably sat for a good 30 minutes before one of us nut up enough to stand up and start the hike back to our trucks.
I still have no idea what that light, or what that... other phenomenon was or if they were in any way connected. But it remains the scariest night I've ever had in the woods. That was 5 years ago now, and texting my buddy to refresh myself on some of the details, he told me how bad he was wishing a bear would leap out of the trees, because then at least we'd know it was something we could defend ourselves against.
