I'm not sure of why I think this (maybe because Bowie always express occultic themes in his lyrics), but to me the song speaks of the relation between him and another ethereal entity (a demon, if you will)...he danced with it too long (to go back)...and the 'something in the air' express this invisible things that regular men don't know about.
