While it's unlikely you've experienced a doppelganger (a physical double of yourself), it's quite likely you have numerous googlegangers -- virtual doubles -- people who share your name and whose hits are mixed with yours on the result pages of a Google search.
I don’t have a googleganger; my name is unique. But my maiden name gets a few pages of hits, among them a firefighter, realtor, yachtswoman and psychologist. Until I noticed that one had been a guest on Sally Jessy Raphael’s TV show, I’d forgotten that I was once an on-air caller to her 1980s radio program.
That maiden self did come close to having a doppelganger. I walked into my small-town high school as a freshman and discovered that my 'til-then unique first name was already in use by an outgoing, assertive senior. (Three years older + popular = very intimidating.) Unbelievably, she later married a man with my surname!
Who are your doubles? What details about them spark energy?
