These are going to be somewhat of the norm now... we should practice keeping fear away from our hearts...
When I feel the dark creeping in... I immediately split the air molecules in the direction the force is coming from by extending the arm with your hand flat like the edge of a spear... and cut the air with your hand like a hot knife through butter.... I then cross it from left to right..... this has always helped me...
Do not fear them... your light comes from a higher source ... they should fear you
