Some time ago, I took a picture of what I class to be a true orb. The pictures you will see are definately not dust as the light anomaly was seen with the naked eye before taking the photos. It was a small ball of light, glowing from its own energy that came into the living room from the hallway. It stayed for around 30 seconds then disappeared into the wall without leaving a mark. I have thought of the theory of ball lighting but this would surely burn the surface of anything it touches and is extremely rare. Are these orb pictures a ghost or spirit manifesting, are they paranormal or are they some other kind of phenomena?
