We are energy. That much has been proven. There are literally millions upon millions of electrical currents running through our bodies at all times. Synapses are firing, messages are being carried telling our muscles to move, our hearts to pump, our ears to hear, eyes to see, and brains to translate the massive load of information being brought to us every millisecond. We are walking miracles of science....that we as of yet do not fully understand.
We are more than just organic machines, however. Something beyond our physical bodies sparks us to life. We commonly refer to this spark as the soul. This is the source of our consciousness, our Chi or energy. This energy brings the body to life. It's what animates us, and when it's time for that energy to leave because the body is broken or in the process of breaking down beyond repair, that energy is freed. So where, exactly, does it go, and what form does it take? That's where a writer's imagination kicks in, and in my case, leads to some fun 'research' in the form of a little ghost hunting.
I've caught quite a few orbs when out shooting pics in graveyards in the middle of the night. The following pictures were taken not too far from my home. It's important to note that on the two separate nights out, there was no measurable moisture in the air. Both were cool, dry nights. Therefore, I can't dismiss the various orbs caught on camera as simply moisture, especially in view of the different shapes and colors, and the definitions of the outer edges.
