Fear cripples the fearful, it causes paralysis; temporary and sometimes permanently, fear can be a hinderance, a barrier, a force sheild from which the fearful cannot get from behind. The fearful stay transfixed, cowering. Fear is powerful emotion, it is a protective emotion, we need fear to protect ourselves, fear can be constructive and it allows us to prepare for impending danger but fear can also be deconstructive, breaking us down, having us cowering from imaginary vilans and shadows and what would be positive experiences. Fear can rivit us in place, stop us from living life to the fullest, stop us from enjoying life, render us powerless, make one unsure about everything. Fear is contagious - scream "fire!" in a movie theatre and watch the terrible domino effect. We see the fearful and we become fearful too. People are running we run too - fear is contagious that way. Fear can also breed negativity. Fear without reason is unnecessary and uncalled for. Fear sinks when one is in the ocean and fear will sink on land.
