A buzzer in a dream heralds the coming changes in life. However, it never indicates the direction in which these changes are to take place.
see the buzzer - your plan will fail
to see the buzzer but not hear it - do not attempt something that you are unable to achieve
hear the buzzer - expect good news
ring the buzzer - make someone happy by accident
the buzzer to the door - you need to be more courageous in a certain situation.
