What Are Those Mysterious Spherical Orbs?

revoaction, according to what I've read, the blue orbs are very highly advanced entities; they aren't malevolent.
 
I had several members on a different discussion board talk about their experiences seeing the blue entities/orbs. One of them saw it in the form of a human standing in his bathroom. It gave off a light blue glow.  He said he smiled at it and it smiled back, then he left the room. 

I don't think you should fear this being. Actually, if they are as advanced as people say, you should feel privileged they chose you for a visit.  

Very interesting.  :)
