A dense forest is a type of forest that has a lot of canopy trees and thick undergrowth. A dense forest really looks impermeable and consolidated if you view it from afar. The very imagination of getting into a dense forest is spine-chilling.
However, the density of the forest does not necessarily translate to danger and impermeability. If you could get near the dense forest, you would realize that it is possible to find your way in and around it.
People judge by appearance. Sometimes when we see a person thick and tall, we tend to fear him outright as if he is a monster without giving ourselves the chance to know what the person really is.
I have seen people, men, whose stature looked terrifying, yet approaching them, I realize they are as humble as lambs and as peaceful and calm as doves. Do not be frightened by mere appearance.
