Sounds are a blessing

As I close my eyes and listen, there is a whirling so low but audible as it works that could not be heard earlier with the loud overhead sound goes with the motor and fan blowing hot air.   The sneeze is often and quick. Are there dust mites? Where did that ? There are other whirling machines blowing. The tap, tap, tap of something distracts me from the whirling machine. The taps are inconsistent, not like morse code, but yet steady, sometimes quick and furious, and other times only one or two taps. The edges are echoing the still air back and forth to my ears as if I am under water and the silence keeps me from know where to turn. The whirling is getting louder as it becomes more quiet every where else. Just tap, tap, the sound of breaths going in and out, tap, tap, now the whirling machine comes back to my attention. It is time to come out of this silence.
