When I was a young pre teen I used to live in a big house that was just touching the edge of a small forest acre. The mossy forest was filled with lively ferns, moss, and mushrooms, and shiny rocks. It was such a beautiful eco friendly nature spot. Anyway getting back on track, Oneday I was standing in front of the forest opening and than I heard this growling noise coming from the forest. It sounded like it was emitting directly at me standing at the boarder of the driveway and the forest ground. I got so scared that I ran away thinking it was a demon. years later I heard the same noises coming from a bush that overgrew a really tall tree stump that was taller than me! The bushy tree stump was at a park beside a high school.
