A man who encountered his doppelganger when he saw him sitting in his seat on a flight spoke of his "total weirdness" when they found themselves checking into the same hotel.
Neil Thomas Douglas, a photographer from Glasgow, was travelling to Galway via London Stansted on Thursday when he came face to face with the bearded stranger.
"When I got on the Ryanair flight, there was a dude already on my seat - when the guy looked up, I thought: 'He looks like me'," he said.
"We had a big laugh about it - everyone around us had a laugh, we took a selfie and that was it."
But later that day, a further coincidence had them checking into the same hotel in Galway.
But the coincidence didn't stop there, they later bumped into each other again having a pint at a local pub.
Mr Douglas added: "Later that night, I went to the pub and again, there was my twin. Total weirdness. We had a laugh and a pint."
Despite their familiarity, they both parted ways without giving each other their names but their encounters have been retweeted thousands of times.
And other doppelgangers are also beginning to emerge:
