Hylophobia
The Fear of Woods or Forests
Hylophobia Definition
"A psychological disorder defined by an irrational of wood, forest or trees."
So basically you cant go camping, backpacking, mountain biking, or off-roading.
I could not live with this disorder, the woods, forests, trees, and even wood in general is my favorite thing in the world. I don't understand how someone could acquire such a weird irrational fear. But if someone had a very traumatizing thing happen in the woods that would make sense.
Video Games
There have even been video games made by cult producers. The name of the game is Hylophobia. You could also consider the first "Slender Man" game where you are being chased around the woods by you guessed it Slender Man. Basically you have to walk through the woods finding random objects but at the same time you are being chased by whispers and by skulls popping out at you. I would include a video clip but all of them cuss.
Treatment
Like most phobias there are no true treatments. You can be prescribed to medicine to help suppress the symptoms of Hylophobia or under go therapy, counseling, hypnotherapy, psychotherapy, and Neuro-Linguitsic programming.
