Scrooge was never a ghost in the story
no. Marley is the ghost.
He plays Scrooge, young scrooge, middle age scrooge, older scrooge, christmas past ghost, christmas present ghost, and christmas future ghost.
When Marley's ghost visited Scrooge he warned him about the ghosts and his behaviour.
The last ghost does not accuse Scrooge of any deed. he, the Ghost brings a vison of what me be. This vison shows a the grave of Scrooge that very Christmas
The Ghost of Christmas past brings Scrooge to a party at Scrooge's first employer, Mr Fezziwig's.
When Scrooge touched the robe of the ghost, he felt a chill run through him and it caused the ghost's form to dwindle down to the size of a child. This hinted at the spirit's fragile nature and the impact of Scrooge's actions on the ghost's existence.
The first ghost to visit Scrooge was that of his business partner, Jacob Marley. Later Scrooge was visited by the Ghost of Christmas Past, Christmas Present and Christmas Yet to Come
The only ghost to have this effect was the Ghost of Christmas Yet To Come. This ghost did not speak only gestured. This unnerved Scrooge especially when Scrooge was seeing the death of someone (who we assume Scrooge thinks it might be him) and the ghost does not confirm of deny this fact but responds with taking Scrooge to scenes of people talking about the sudden death of "the man". During this Scrooge realises the man is in fact himself and finally he is taken to the grave of "Scrooge" where he sees his existence in eternal torment.
The ghost takes Scrooge to the Corn Exchange - Here Scrooge would have been seen on a daily bases in his familiar place. On his visit with the ghost Scrooge hears business men speak of a sudden death and asking what will happen to the deceased properties. The ghost does not get involved in any discussion throughout his visitation to Scrooge
The Ghost of Christmas Past is accusing Scrooge of wanting to extinguish the light of truth and self-reflection that the ghost represents. By asking to put on his cap, Scrooge is implying that he wants to avoid facing his past and the lessons it holds for him.
He steps into Scrooge's bedroom while Scrooge is a asleep and startles him.
