Usually the message of quietness is peace, tranquility, low stress, etc. However, "deathly quiet" is sometimes the descriptor for the type of quietness that is filled with anxiety and fear, or abject sorrow. There are many types of quietness... could be two people in love and they don't need to say a word to understand each other... or it could be the silence of hurt and anger and "not speaking to one another" that means exactly the opposite.
