Hmm, perhaps not supernatural but a bit nerve wracking.
When I was 23, I went backpacking alone in the Indian Heavan Wilderness. One night I was sitting by a small camp fire, I heard an animal scream in the distance and wondered what it was since I had never heard anything like it. Over the next hour the screams came closer to my camp until they were about 200 yards out in the timber. I could hear a heavy animal moving around but couldn't see anything due to an overcast sky and being night blind due to the fire.
I know it wasn't a cougar, I have heard them plenty of times. An you never hear them moving around. Bears don't scream and nothing else around here does either. I never did figure out what was doing all the screaming and moving about.
I spent a long night sitting up by what went from a small fire to a bonfire in no time at all. Weirdest experience I have ever had in the woods.
Local indian lore calls that area Sasquatch home turf. There are lots of legends about the local indians having encounters with them in that specific area. Definately put a tingle into the old nervous centers that night.
I spent three more days in the area and never heard another thing.
