Some people believe that orbs are more than dust particles or drops of moisture on the lens--they are proof of guardian angels, captured on camera. When these "spirit orbs" or "angel orbs" appear near a single person or a group of people in a photo, it's a sign that they are blessed with the goodness, positive energy, and protection of angels. When orbs appear in a particular location, it's also a sign that angels are hovering nearby and the location is particularly blessed.
