I was walking down the street when I came up behind a man. I watched the back of his head and noticed his hair color was the same as mine, combed in the same style. He was my size and build and wore the same type of clothes I usually wear. Not the same but the same style. As I looked I became increasingly taken with how much this man looked like me; the same gate and mannerisms. He was even smoking a brand of cigarettes I sometimes buy. The strangeness of the situation grew until I could not shake the feeling I was staring at the back of my own head. I became increasingly disoriented. I felt nauseous, the ground began to shift, my heart raced, my breath became shallow and rapid. I could take this no longer. I had to do something. I reached out and tapped the stranger on the shoulder....
How can I explain the shock of the next moment?
For when I turned around to see who had touched me, there was no one there!
