Scrooge was to see his own demise. He witnesses peoples reaction to his passing and sees that he will die a very lonely man and in doing so suffer eternal torment as did his partner Jacob Marley before him
The last image that the spirit showed Scrooge was his own grave, with no one to mourn him and only the cold, harsh reality of his death. This vision shook Scrooge to his core and prompted him to make a transformation in his life.
It was Bob Cratchits home where Scrooge sees what Bobs family think of him and learns, whoo bob is loyal and that Tiny Tim will not see the next Christmas if "things" do not change
Uncertainty and disbelief
There were four spirits that visited Scrooge that night: the Spirit of his dead partner Marley; the Spirit of Christmas Past, who "took" Scrooge back in time to Christmases--both good and bad--when Scrooge was younger; the Spirit of Christmas Present, who "took" him to his nephew Fred's home and the Crachit's home, to show him how joyously they were enjoying the season, in spite of being poor; and the Spirit of Christmas Yet to Come, who "took" him into the future to scenes relating to Scrooge's own death. Scrooge convinced the last Spirit to leave by promising it he would change.
to see how many people celebrate the festive season
Jacob Marley for foretelling his rate and the three ghost who take Scrooge through his life and help him see what the spirit of Christmas is about
So Scrooge will see the life his loyal employee Bob has and how he manages to live on the meager wage he pays
The grave yard
Scrooge is visited in his office by Fred his nephew and 2 portly gentlemen seeking a charitable donation to help the poor. At his home Scrooge is visited by the ghost of his ex-business partner, Jacob Marley and then by the Ghost of Christmas Past, the Ghost of Christmas Present and the Ghost of Christmas Yet To Come.
Undue literary license. I can"t recall anything Maritime in (Scrooge) of course Seeing the Light- has spiritual overtones.
In the last vision that the ghost shows Scrooge in "A Christmas Carol" by Charles Dickens, Scrooge sees his own lonely death, with nobody mourning him. This vision serves as a warning for him to change his ways and avoid a similar fate.
It was the Ghost of Christmas Present who alluded to the fact that Scrooge did not recognise him or any of his brothers. This was because Scrooge had not embraced Christmas before. His only close relationship with that we see is when apprenticed to Mr Fezziwig
