The question of how dark energetic forms find entry into an individual is a profound question to contemplate.  Not all individuals are vulnerable.  There are energetic forms that are opportunistic in nature, looking for a weakened and vulnerable person.  Sometimes the energy has the ability to jump from one person to another.  Sometimes the energy has just been there for an unknown period of time.  No matter, the case is the same … there exists an opening, a tear in the fabric of the soul.  This I refer to as a soul fracture.  It is a wounding that has not yet found its way to a healed state.  Traumas of many makes and descriptions are the basis for the fractured soul.
