Orbs are very common and a lot of people see them, especially showing up on photographs!
There are different causes for them, but the one thing that is common about them is that they are all energy. Everything is comprised of energy. All forms of Spirit, all emotions, thoughts, feelings, and even physical material things are all energy. There are different degrees of variance that make them all up, but they are all energy based!
Sometimes these “blobs” of energy, particularly the ones we see closest to us, are manifestations of our own energy. Particularly when one is experiencing a strong emotion, that person may emit a ball of energy, or a thought form.
Other times we will witness “paranormal” activity or spirit energy in the form of an orb or ball of light. Sometimes the light has color to it, and reflects the type of thoughts or emotions in that energy.
Mediums will often see or feel the energy of one who has crossed. Many times we experience these visitations ourselves and can pick up on the energy pattern of the soul who is contacting us.
Sometimes we can also witness balls of energy around various shifts in energy. Some people may see strange lights or wisps or orbs before a thunderstorm, or when there are solar flares.
Again it is the witnessing of energy patterns. All things emit energy, our thoughts are powerful, and many people don’t realize just how so, because we are not taught how our thoughts or emotions effect our reality in our physical realm.
Orbs are just one form of energy that happens to get a lot of publicity lately, especially being captured in photographs! These are emotions, thought forms, or perhaps Spirit forms traveling around us.
They are not to be feared in anyway! Respect their energy and they will respect yours in turn!
