A tour guide got the fright of his life when he spotted what appeared to be a 'ghost' waiting at a bus stop.
Of course, why exactly a spectral being would need to use public transport is anyone's guess, but Ivan Rubil - a tour guide in the Croatian capital Zagreb - spotted that the person hanging around waiting for the bus had see-through legs.
Rubil's job as a tour guide sees him taking Brits - among others - on tours of the city, including some of the 'haunted spots'.
However, this time, it was him that got a spooking as he captured the strange figure on camera.
The 30-year-old took the photograph because he spotted two nuns at the bus stop and thought they looked like bus conductors.
So, thinking he'd spotted a funny photo, he got out his phone camera.
However, upon closer inspection the apparition was revealed, as the woman in a brown coat that was also waiting had transparent legs, meaning that he could see the bus stop line through them.
Since he shared the photo, loads of people have commented on the strange nature of the photo. Some believe it's just a trick of the camera, but others think it could be something more.
Ivan explained: "So I uploaded the photo to Facebook and had one of my friends comment, 'There's a ghost on your photo!'
"I didn't see it for at least fifteen or twenty minutes - but then I saw it.
"For a few hours after it was pointed out to me, I was a little bit taken aback.
"I've gotten some complaints that it was just my camera, but I've tried to take similar photos and not gotten the same effect."
"I'm still not sure that it's a ghost, but it was definitely fun!
"I think ultimately, I do agree with the people who said it was a mistake of my camera, but it's not easy to explain.
"I don't usually believe in the supernatural, but when I have evidence like this, I cannot be so sure.
"I'm keen to believe, but I'm not so sure. I would say I'm agnostic."
He captioned his original snap: "I took this photo because I thought it was interesting how the two nuns look like they're going to enter the bus and check everyone's tickets as conductors.
"Much later did I realise that the woman in the brown coat near to them could be a ghost!!!"
Speaking of his job, and the potential for ghosts appearing in the city, he added: "Tourists usually come to see Croatia's medieval towns, national parks and beaches.
"But I do sometimes do ghost tours. Zagreb is known for its haunted spots and there's a lot to say when I'm giving these tours.
"These old medieval towns are quite superstitious and in Croatia, you can still sell a lot of stories about witches and ghosts."
