Finding and looking at a stranger that looks exactly like you is a weird experience. Some say that we all have seven doppelgängers living across the globe and most of us will never meet our twin strangers.

The latest to discover her doppelgänger using this online service called 'Twin Strangers', is Shannon Lonergan, 21, from Ireland. She found her identical twin stranger Sara Nordstrom, 17, who's from Sweden.

Both said the experience of meeting their own lookalike is completely strange. Although they can hardly take the idea in, they had lots in common - same blond hair, pout lips, facial expressions and many others.

Sara and Shannon met up in Dublin after they both had signed up to the site and found their resemblance very strong that they were quite frightened but overwhelmed.

The similarities of these two girls are really incredible that even Shannon's family struggled to spot the difference.
