whail most of them sleeps

why do most of the people are afraid of dark or at least feels uncomfortable in it? is it because you can no see what is in front of you? but isn't that a marvelous feeling... no one thou can see and no one can see thee.. yes maybe there is someone behind the curtain of night but that just makes it all more interesting. to go into the unknown.. do not fear the night. it is true said that the biggest fears one can have is fear from the unknown. for me the night is cover, the night is home and I do not have fear of the dark and who ever is hiding in it. I greet them with an delighted smile no matter can I see them or not. do not fear the night my child, do not fear the unknown.. as it is only thy head who makes it all so fearfull. do not let thy head rule over thou. as it only wants to make thou weaker. but why is that so? why do our heads makes us fearfull?
