My partner worked late nights last year. The drive home was about 45 minutes, part of which winds through huge mountains with no cell service and virtually no light pollution. He was on his way home one night and we would usually talk on the phone for most of his drive. There’s a dead zone halfway up the mountain which led to our call dropping. A sense of dread washed over him as he looked to the side of a car and saw a black, humanoid silhouette running on all fours directly beside the car. He was going at least 60 mph, way too fast for any known creature in the mountains to keep up with. This thing chased him up until right before he pulled into town. It turned and ran up the hill. After that night, this thing became attached to us. We went to the gas station one night and I saw this thing standing about 200 feet down the road, illuminated by a street lamp. 5 minutes later as we’re headed home, not only is this thing gone but the street lamp wasn’t even ON. It followed us to Tennessee and back, trailing us in the woods and behind our car the whole way home. There’s a little tunnel that you pass through on the way and of course, right before we drove through it this entity was standing on the stones that make up the top of the tunnel. At least five other people around us during this time frame of january - september also saw this entity. The last time I saw it was in Leicester NC. It was around 1am, my sister and I were sitting in a swing in the backyard and talking. I started seeing this black silhouette running back and forth across the road. I thought my eyes were just playing tricks on me so I tried to ignore it, but it continued to run back and forth for what felt like forever. Little did I know, my sister was seeing it too but she also thought she was just seeing things and didn’t mention it. This entity finally turned and ran up the hill to a neighboring house and that’s when my sister turns to me and asked if I had been seeing this thing too. We got up and BOOKED it into the house. I ended up driving her home a couple minutes later. I checked the rearview mirror and saw it one last time, standing directly beside the light post watching us drive away. I’ve had many encounters with this entity and I will never be able to describe what it was or why it attached itself to my partner and I. It genuinely looked like a humanoid shadow. No visible facial features, nothing except an appearance so dark it reminds me of a void. I haven’t seen it since. it’s been over a year at this point, yet I still find myself scanning all of the backroads we drive down anticipating the appearance of this thing.
