Inside the world's most haunted forest

Where is it: Hoia Baciu Forest is located near Cluj-Napoca, a city in the Transylvania region of Romania.

Area: The forest covers a region of approximately 295 hectares (729 acres). 

What's in a name: The forest was named after a shepherd and a flock of 200 sheep that went missing.

Another name: The Hoia forest is also known as the Bermuda Triangle of Romania. 

Trees: The forest has a number of strangely shaped trees.

Spirals: Strangely enough, all the trees that form spirals do so in a clockwise direction.

UFO: In the late 1960s, a biologist named Alexandru Sift took photos of a disc-shaped object flying over the forest.

Aliens: And in August of 1968, military technician Emil Barnea also took photos of what he thought was a UFO hovering over the forest.

Threat to the state: The communist government eventually fired Barnea, as they believed the paranormal to be a threat to the state.

More sightings: In the 1970s, more unexplained lights and UFO sightings were reported in Hoia Baciu forest.
