Welcome

What are these balls of transparent light we find in photos taken in allegedly haunted places? I won't tell you I know the answer to this question. No one has the true answer to this question yet, but that's part of the job of researchers and investigator.
One of the leading theories concerning what orbs are and the one that I lean towards the most is that they are not the spirit at all. The orb is the energy being transferred from a source (i.e. powerlines, heat energy, batteries, people, etc) to the spirit so they can manifest. This may not even be a conscious thing the spirit is doing, just a natural way they get their energy. This would explain why the orbs are round balls. According to the laws of Physics energy being transferring like that would assume is natural shape of a sphere. This theory can also be tied into the EMF readings we get during spirit activity.
I always approach things with a bit of skepticism, so when I saw all these websites start showing off these photos as ghosts, I was just as weary as most of you. I just had to try it for myself. I took a 35mm camera that I had used regularly for 6 years in all types of lighting and weather and had never gotten an orb or other unexplainable photo before and went out with a few seasoned field investigators on a cemetery investigation. One of the investigators was psychic and she pointed out a few areas we should take photos, so I did. I also had ghost footsteps walkup behind me twice and I turned around quickly and took photos of the empty air. When I got my photos developed, I had these orbs and fog in those photos that I was told to take, as well as the footstep ones. All my other photos were normal. Coincidence?
