Yes, being around lower vibrations can affect you.  Be on the lookout for this.  Some of you are like sponges and soak up the
thoughts and feelings of others.  Regular
cleansing is necessary if you are to maintain peace.  How do you do this?  The recipe remains the same:  Deep, cleansing breaths in nature.  Visualize the pure energy flowing through
you, replacing lower vibrations.  Meditate, and focus on the heart and
healing.  So many do not realize how much
the vibrations of others affect the whole. 
Those who are empathic realize this quite well.  Do your dusting and keep the lens crystal clear.
