Paranoia

I was walking down a small path in the woods yesterday, near the train tracks and the motorway, when I came across a circle of about 20 pale men all on their mobile phones, dressed normally, yet wearing sunglasses. The sun had gone in. I proceeded, pretending not to notice, however they noticed me and simaultaneously turned their heads, and observed my picture taking. I carried on walking on the track until it disappeared, they followed me, and hid behind trees. I walked faster and faster, with no destination, they followed. After ten minutes, I was pretty panicky and climbed onto the 6 lane train tracks, ran across, climbed over a wall and turned back. They had all disappeared. I then found myself in a barn, ran out with an elderly woman shouting at me, and finally ended up in a nudist resort (November!?). Have I gone completely mad?
