Sympathetic Vibration
From The SpiritWiki
Sympathetic Vibration is a term used to describe the tendency of the Physical Unit to be impacted by the Energetic Valence of the immediate environment. Thus, if you enter a room full of negative, angry, hate filled energy, your physical unit will tend to absorb, react, and vibrate with the negative, angry energy. Like a tuning fork, your body vibrates in sympathy with the vibratory tint of the energy that surrounds it.
