This happens all the time.

What you are all hearing is a backscatter return of your
signal.  When the conditions are very good in the direction 
you are beaming you will sometimes hear this echo. 

If you have large high gain antennas you will hear this more 
often - since there is more gain on TX and RX in your high gain 
system.  

Some 6 meter ops have been known to use CW and QSK and 
move the antenna around until they start hearing the 
scatter echoes - they then know they are beaming in a direction
where the band is open.
