Hylophobia

Hylophobia (from Greek hylo, "forest") is the fear of forests. This phobia is commonly developed from dendrophobia (fear of trees) since forests are groups of trees. Other causes of phobia include getting lost in the forests, getting attacked by creatures, worrying about trees falling onto them, and even seeing somebody getting injured or killed in the forests in the movie. Sufferers would avoid going to forests, while more severe sufferers would avoid living near forests.

If the sufferer encounter forests, they may result in symptoms including loneliness, dread, slow breathing, heart palpations, trembling, and obsessive thoughts especially about death.
