I am not sure what orbs are exactly but I have seen one.

We were in bed and I rolled over to face the opposite direction and I just half opened my eyes and saw this round sphere above DH head blue/white. I just closed my eyes like it was nothing then had that " WTF " moment and of course it was gone when I looked back.

Haven't seen it since, but we have parculiar things happening in our home from time to time. It just adds to the charm of the old place that I love so dearly.
