Without realizing it, you may be under psychic attack from negative entities around you.  These entities can be in your your energy field, your loved ones, or your environment.  In a sense, you have become a honing beacon for these negative entities, and in so doing you have opened the portals for the entry of these entities or other negative energies.  When this happens, you may experience sudden physical pains that are “off the chart”, suddenly experience extreme emotional changes that are unaccounted for, or not feel like your normal self.
