Are 'orbs' hiding a real phenomenon?
Before the advent of orbs there were always reports of light anomalies, both in interior hauntings and in various locations outdoors - sometimes associated with UFOs. The major difference between these lights and orbs is that these lights were SEEN by witnesses. It was extremely rare to get a photograph of one but it did happen sometimes. Whether some, or all, of these lights have a mundane explanation, is yet to be determined. The big point is, with so many people getting excited about spurious 'orbs', these light phenomena are being overlooked or even dismissed as mere 'orbs'.
It would be fascinating to know what these light phenomena really are. Some might be fireflies or even reflections but it is unlikely this accounts for all of them. The trouble is, we may never know.
