The photo looks just like thousands of others you can find on the web.
It's most likely out-of-focus dust in the air, lit up by the flash. It's far more usual to hear of it in a ghost hunting context.

This is rather easily disproven. Proof: If you shake out a doormat and then take a photo against a darkish background you will see many hundreds of these 'orbs', their details are 100% the same as the ones on the web. They are simply dust particles and small bits of debris which are floating very close to the flash.
Their appearance varies (depending on the lighting, camera type, distance form camera and type of particle, such as dust, pollen, hair, etc) from opaque white, to rainbow tinted, semi-transparent and sometimes they have 'trails' (caused by smaller fast-moving particles very near the flash) A Lack of understanding general optics and the mechanical aspects of photography causes many people to believe they have photographed something mysterious or supernatural.
Ever examine the air illuminated by a bright sunbeam through your window? Even in calm circumstances there are hundreds of tiny particles of dust, skin, fine fibers and pollen floating thru the air. That they would show up regularly in flash photography is no surprise.
