This happened to me a long time ago and it still haunts me just thinking about it. Me and my family use to take hikes often, just strolling along, running, and sometimes we bring our bikes on the trail.
However our routine changed one time, we were walking on the same trails except we were deeper in then we normally were. I had been going ahead further then the rest of my family.
All of the sudden I stopped dead in my tracks from what i saw, it was a lengthy pale humanoid at the end of the trail that i was about to walk on. I told my mom and she came running, both my mother and my brother told me that I was just seeing things.
