Orbs are a phenomenon that can be seen in photographs or videos, and are typically circular artifacts on an image caused by the cameras flash being reflected from unfocused particles in the air or water. However, some people believe that orbs are transparent balls of light energy that are connected to spirits, and can be spotted in photos or even videos. Orbs of light can appear in a variety of different colors, but they’re most often transparent, black, white, green, red or blue. Orbs are frequently photographed or seen when paranormal activity has taken place, but most of the time, orbs can be explained as dust, insects, mold spores, or pollen. Some individuals believe that a ghost orb is an indication there is a spirit nearby, but this is a topic of debate in paranormal circles.
