That picture in Vietnam is great.
I have seen orbs flying in formation for several minutes in the country side.
THey came over a hil together and their motion was like a bird flapping its wings in slo-mo. Theyt criss crossed eachother and maybe you could say it was like watching two large slo-mo yo-yos about 50feet in the air.
They stayed in this fashion until dissapearing over the tree-tops...
Orbs I believe are very playful!
and like to remind people to have a laugh and not take anything too seriously!
Seeing an orb is alos personal validation as well I believe.
Check out my Orb pictures from Avebury/Stonehenge area this year!
Very bright and 'Sunlike'
I have also friends with experiences of orbs. One in partiucalr grew brighter and brighter befroe flying out the room after my freind was doing healing in the room it was in.
He had been healing the room as there had been odd occurences and it may have been a shackled spirit she helped free?!
Maybe some one can clarify this a little as I am not an expert in these things.
All the best people,
LOVE
