Do twins have twin doppelgängers?

Your question is valid ThomasThomas.
Residing in the world of flesh though places me at a disadvantage of answering knowingly from a ghostly perspective.
Perhaps this question should not be carried to any government agency for I suspect there would have to be billions spent to attain an answer suitable to both the flesh world and ghostly world. This being the time of political correctness and no offense intend to the living and nonliving.
May you and I keep this question to ourselves?
