the dark is one of those things that are always there. it can benifit us and hurt us it can also scare some people. like me i am scared (do not ridicule me) heres how it works. fear... fear is something we all face. but the cause of the fear of the dark is the fear of the "unknown". when its dark people cannot see whats around them and that causes paranoia. paranoia is where you feel your being watched without your knowing or feel someone is out to get you. thats what makes us afraid. we are afraid what could go wrong might go wrong. you think you heard something move in your room or you heard a noise out side. this keeps you up all night and there is only one thing that helps... light. light lets us see our surroundings. it gives us a sense of security.
