Recently I have been growing more aware of when I look at people in a certain way I feel an energy conflict in my eyes. It is like their eyes send out energy and mine send out energy. I have had a number of experiences where they send energy to me and it goes into the blocked part of my left eye, and I feel it there. Then I push it out of that blocked part because I don't want it there, and when I push it out of my eye it pushes at their eyes and they immediately look / flinch away.
People unconsciously "send out" energy through their eyes. That is why it has always been considered "rude" to stare, because it is usually sending energy with "negative" intent. Energy follows awareness.
If you can feel the energy from others, there are a couple of experiments that you might want to try...
Look at yourself in a mirror and imagine that the mirror is looking at you. You should be able to feel the flow.
Also...
Spend some time outside on the night of a full moon. Looking at the moon, when you feel the flow, you will understand how various cultures started worshiping the moon.
