Seeing a doppelganger was once considered as bad luck or something evil. They were seen as an evil twin or a paranormal creature.

If you think that these are just folk tales, the science back then didn’t offer optimistic explanations either - seeing your exact replica somewhere was a sign of epilepsy or schizophrenia. So, you can see why seeing a doppelganger was not something enjoyable those days….

Now, with science progressing, and with people’s understanding of how large the human population truly is, we can easily accept the fact that somewhere, a glitch in the system produced our exact copy. After all, so many of us have common ancestors, without even knowing it…

People are sharing their doppelgangers photos, and we have selected some of the best. They will leave you wondering if you have a double out there….
