I had a similar experience. When I was around 18, a friend and I decided to camp deep in the woods and just as we were drifting off to sleep we heard a ungodly scream (screech owl) that scared the bejebers out of us. Both too manly to admit it, we decided that the mosquitos were too bad to get any sleep and made the slog through the woods by flash light to my parents house were we decided that the shed would provide enough cover from the mosquitos for a good nights sleep. Never heard a screech owl before or since then.
Another time when I was a teen, I was out hunting pheasant/grouse, in an area that always made my skin crawl. It was an old home stead the only remains were the foundation and wood debris from the structure scattered around. Local legend, (teen neighbor), had it that the last owner was sitting by the window one night and looked out to see the devil looking at him, he ran out never to return. The reason I hunted there was that the old homestead had apple trees on either side of the very overgrown road and was very good spot for game.
Well one overcast windy day just before dusk, best time for birds, I was walking trough the twisted leafless branches of the apple orchard when I passed one tree trunk and came face to face with a pigs head hanging from a branch, two feet away. I was further startled by the very audible gasp coming from my own mouth. Upon further observation I noticed a bear trap right below it, relieved that it was a hunters baited trap and not some satanic offering, it did little to slow my manly retreat from the area umm before the rain started.
