Are theree anu other photos of this location from another day? I would have to say that maybe the host sprayd some glitter on the wall for the party, but I don't know because I was not there. If you have other photos from that wall from another time and there is 'orbs' please post. Also look at hte type of paint being used. If the paint is latex high gloss with a textured wall, great fx.
It's something reflecting the flash. If it's actually on the wall, it's likely either nail heads, or a moderately reflective spackle used to patch holes. But it could easily be airborne dust particles. It's definitely not tiny ghosts clinging to the wall like flies.
