Saw this topic, and actually joined Reddit to be able to post. Years ago, while hiking with my girlfriend in a very isolated area, we discovered we were being stalked. It was late in the day, not dark yet, but getting there. We were on a path, with heavy woods on each side. We could hear movement in the woods - sounds of leaves rustling, branches snapping, etc. that seemed to parallel our path, and matched our movements. However, we couldn't see anything. We tested it...stopped walking to listen, and the noise would stop. Start and stop again, and it would match our movements. Finally, I left my gf on the path and walked toward the noise. I did see something that, to this day, I can't explain, and it scared me very badly. When I saw it, it had been behind a tree, and quickly ran away. It was probably 30 feet from me when it took off. Humanoid shape, extremely tall and thin. I have always described it as being almost skeletal. It was pale white. I'd estimate it was 7 feet tall or more. It ran away very quickly, which is a good thing because I was paralyzed with fear after seeing it. After a minute, I got my wits back a little, and went back to my girlfriend, and we got out of there. Luckily, we didn't have far to go. True story, and it made me realize that there are unexplainable things in this world.
