Orbs in photographs

I often hear about orbs being ghosts or similar, so here's a real genuine photograph of lots of ghosts....   or maybe not, it's not photoshoped, at least the orbs are not, I have tweaked the exposure as it was a compact camera in quite poor light.
So the big question is why are ghosts attracted to a disused toilet??? And who could be so heartless to abandon it in the first place?   More importantly who cares?  Not me that's for sure!.
