In this scenario, we make sight of a person we know as “Smith,” from some distance. He may be half a block down, or perhaps across the street. Now Smith isn’t someone we would encounter often, even if we were to repeat the very same footsteps every day. Smith is barely an acquaintance — a friend of a friend, perhaps. We might run into him once, maybe twice in a decade, even in our medium-sized city.
   But as we near Smith and he comes into better focus, we notice he looks less and less like the “Smith” we know with every step. As we catch up and pass the gentleman we realise we’ve mistaken him for someone else, and that he bears little resemblance to our “Smith.”
   It is then that we turn a blind corner and run into who, but the very same Smith of whom we were given some sort of Fortean “advance notice.”
   What are the odds of this happening? More than once, as it has?
   It appears that “Fake Smith” was a premonition given to us in the form of a fading Doppelgänger — a “preview” of the real Smith.
   Again, odds are stacked against this happening more than once in any given person’s lifetime. If it is not an omen bestowed from the beyond, could it be some latent form of “psychic radar” yet undeveloped in the recesses of the mind of current-day homo sapiens?
