A woman has discovered her trail camera has captured a mysterious object lurking in the images.
Trail cameras can be an incredible tool in monitoring animals and other happenings in a particular area.
However, what Carolyn saw on her machine has her seriously questioning reality.

She uploaded two images from her camera to Facebook and wrote: "I just checked my camera that is deep in the woods behind Mount Si in the Snoqualmie Valley.
"Either there is a sasquatch in the area or I’m being expertly pranked."
The Snoqualmie Valley is east of Seattle, which is in the prime region of Bigfoot sightings.
Live Science reports there have been more than 10,000 alleged sightings of the elusive creature and the majority of those are contained in the region of Washington, Oregon, Northern California, and Canada's British Columbia.

That makes this potential sighting in the Snoqualmie Valley all the more juicy.
One of Carolyn's images show an odd-shaped body in the left-hand side, before it seemingly appears just off-centre in the second picture.
Whatever it was, it was on the move. It also looked fairly hairy and large. Sounds like prime Bigfoot territory.
While these images might seem like fairly conclusive evidence of Bigfoot, it's nothing compared to the footage that was captured last year.
Nv Tv - the 'largest database of Bigfoot, Sasquatch, Yeti, Skunk Ape, Yowie, Werewolves, Dogman' and other cryptid content - posted the video on YouTube back in September, saying in the title: "Incredible Muscular Giant Sized Sasquatch On Camera!!"
It also adds that the footage was captured in Idaho, USA, while going on to say in the video itself: "After watching the clip and looking at the amount of detail in this 'suit' we thought this is something real you can not buy online.

"The Bigfoot in this video looks very real and you can even make out the heavy build and all the muscles which is hard to replicate using a fake suit.
"Plus who in their right mind would rent or buy a suit just to pull off a hoax?"
Paul Seaburn of MysteriousUniverse.org said: "Whatever this is, it's BIG. Big head, big butt, big body, thick legs, large arms.
"That would have to be a pretty large human to be a person inside of a costume.
"Along those lines, if it was a human in a costume, its wardrobe assistant managed to find one with a pretty snug fit.

"You don't see Bigfoot impersonators in costumes that realistic... if this is what Bigfoot really looks like.
"The gait is a normal walking gait - nothing bearish or ape-like about it."
