When we speak of 'orbs' what do you think they mean?
Orbs of light are sometimes perceived by the eye, sometimes by the lens in photos taken later.
ORBS OF LIGHT is a website with some great orb photos.
It depends who's talking about them as to what their interpretation is.
Aliens?
Physic connections to spirits?
Transcended beings?
Ghosts?
What we do know is they are a presence that seems to be drawn when we are connecting, centered, and often when we are bringing through higher knowledge and teaching. Often in beautiful places in nature-are they there because we feel a certain way?
I've seen them inside, outside, fireside. I've seen them in dreams too. I've seen them with eyes open, eyes closed. I don't think there is only one answer.
