The correct answer to this open question is the following.
There is no question here. It is just a statement.
Furthermore, you did not specify if this statement belongs to a novel, a play, a movie, or what?
It is so difficult to help you without the question and the proper references.
However, trying to help you, we can infer that you are talking about the ghost in the play "Hamlet," written by English author William Shakespeare.
Being that the case, yes, the appearance of the ghost helps create an eerie mood and grabs the audience's attention. Shakespeare, being the expert writer he was, knew how to create suspense in the readers. As the ghost does not speak, this adds mystery and suspense to people's minds. The audience would probably want to know more about the ghost in the king's clothes and ist purpose to appear. Most people could think that the ghost is there because it has issues to resolve. 
 
        
             
        
        
        
Answer:
I think it's similes. 
Explanation:
You can immediately cancel out allusions (reference to well-known person, place, or event outside the story) and hyperbole (an exaggeration, not to be entirely believed) leaving simile and metaphor. Because the word "like" shows up twice at the beginning and end- the roof came down steep and black <em>like a cowl</em>, their thick-leaved, far-reaching branches shadowed it <em>like </em>a pall- we can assume the answer is simile. Hope this helps!
