Being from a formerly and still in large part rural part of Minnesota and having a dad who hunted raccoon I got taken from time to time on a hunts from a young age which was done at night with hound dogs, and I also spent every summer night I could as a boy starting around seven or eight years old sleeping in a tent outside, Mostly so I could run around all night as I learned that trick from others early on and never encountered anything outdoors that caused me any kind of real fear until I was fifteen years old.
Long story short, this was before the internet and one of my oldest friends who I started sneaking around with at night in my teens is half Navajo and from his Navajo side, he would hear stories and then repeat them to us trying to scare our group with stories of Skinwalkers which are basically werewolf type witches that can shapeshift.
Well, one perfectly calm and quiet night just he and I were out for thrills and walking down to a dead-end dirt road with the rocks crackling beneath our feet on a road that was adjacent to a swampy area when something very nearby started to whine which to me sounded like an old police siren from the 60s' or 70s', and at the moment it started in the back of my mind I expected to see the lights of a squad car come on somehow but then the sound changed to the most fearsome bone-chilling roar that I have ever heard and we froze in our tracks and when I could finally move my head I looked over at him and saw in the moonlight a single tear coming down from his eyes that were as big as saucers Lol. Let me tell you that this thing spoke a universal language and it said very clearly that it was angry and to leave now, which we did as promptly as we could.
When our feet came free, without saying a word we ran in the opposite direction as far as we could and I tell you that even then in my mind I knew that whatever made that sound if it wanted us it had us but we ran and then walked directly back to his house never to sneak out again and he tried to pretend like it never happened and not to speak of it as Indians often do but I never let it go and have told the same story now to anyone who would listen for about twenty-five years.
There is more to the story but them are the basics the best I can tell them here so be careful out there!
