Light and Dark

I'm your security on those dark dreary nights
I take away all your false fears and frights
I illuminate corners eliminating the shadows
I'm here to drive off all your dark foes
For without me there'd only be night
I'm always there when your in need of light

In the mist of the night I appear
In your sleep I cause you fear
When I come your courage fails
Your fear of me you can't unveil
For in my presence you'll find fear
But in the light I'll disappear
