People often wonder about psychic energy. What is it? Everyone is believed to have Chakras (which are thought to be wheels of energy in the body) and an Aura (which is thought to be a subtle emanation surrounding the body). Think of these things as your psychic energy.
Everyone has their own personal space. This is where psychic energy resides. Psychic energy is believed to make up that very important personal space. Generally, people are aware and are protective (maybe without realizing it) of their personal space.
