This happened when I was 16 years old.
Living, as I did, in a small town in Western Massachusetts I had often seen more wildlife than people while out walking and so I felt comfortable being near wildlife. I used to walk to my girlfriends house most everyday and walked back home after dark, it was about 2 miles each way. On my way home there were few street lights, maybe 3 near her house. It was beautiful when the stars were out, but on a dark night I could barely see the road under my feet. Well, anyway, there was an area about a 1/2 mile from my home and about 200 hundred feet long where I felt I was being closely watched and silently followed by something that wasn’t friendly. As I would go by I would feel the hairs on the back of my neck raise. I could feel this during the day too, but it was more intense at night. It was always in the same spot. This feeling always started and ended there. Eventually someone built a house off the road in that creepy feeling area. I noticed every so many years it would be up for sale. Was this the cause? I never asked any of the owners about their property or house, but I wish I had!
