Perhaps it's a physical attribute or an emotional response you have. That person or being is really an archetype. They are blueprints for our inner selves. The part of yourself that connects with and expands to include all of the universal images and forms. When you connect with an archetype you are communicating with the energy that mirrors your own energy.
People contact their archetypes without knowing that they are doing it.
Many years ago before I knew what I was doing, I was riding in a subway car late at night. I noticed that I was sitting in fear and when anyone looked at me I felt scared. I decided to pretend I was a police officer. All of a sudden my body sat up straight. I had a different look in my eyes and I was not afraid at all.
