It is not always dark out there, you know. For you carry your own torch inside of you. You are the light within the darkness and the darkness is just a place where you have not been yet.
So, do not be afraid of the dark for such fear serves no good and in a way the dark is just an image of your fear, for in reality the dark holds nothing for it is nothing.
The light within you, you do not fear. The light within you is always with you, so do not fear the darkness. In a way by fearing the darkness you are denying the light within you.
So, go on your journey towards places that have yet to be discovered. And as you discover them you will bring light to them and they will become real and you will have broadened your horizons.
