The second place visited by the Ghost of Christmas Past and Scrooge were the streets of London where the people were celebrating christmas, exchanging Christmas greetings and many were seeing food
Undue literary license. I can"t recall anything Maritime in (Scrooge) of course Seeing the Light- has spiritual overtones.
Scrooge wanted the Ghost of Christmas Past to take him away and show him no more after seeing Belle with her family. He was overwhelmed and emotional seeing the scene and wanted to stop dwelling on the memories.
There were four spirits that visited Scrooge that night: the ghost of his dead partner Marley; the Ghost of Christmas Past, who "took" Scrooge back in time to Christmases--both good and bad--when Scrooge was younger; the Ghost 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 Ghost 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.
Scrooge learned from Tiny Tim that compassion and kindness are more important than material wealth. Seeing the struggles of Tiny Tim and his family helped Scrooge understand the true meaning of Christmas and the value of caring for others. This realization prompted Scrooge to change his ways and become a more generous and empathetic person.
In the story "A Christmas Carol" by Charles Dickens, Scrooge's fate is shown to him by the Ghost of Christmas Future. Scrooge sees his own gravestone before seeing Tiny Tim's empty chair. This suggests that if Scrooge does not change his ways, he will meet the same fate as Tiny Tim - death.
Its his lonely self
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.
When the ghost/spirit of Christmas future showed Scrooge that people were stealing his belongings and that no one cared when he died , he realized what a sad and horrible life he had lived. The lesson he learned from seeing that was that people should be valued, loved, treated kindly and that people are worth more than material things.
In the original book A Christmas Carol by Charles Dickens, the third spirit is apparently the Ghost of Christmas Yet to Come. It never says anything to Ebenezer Scrooge, merely gestures, and is described as a hooded phantom, possibly like the stereotypical Grim Reaper.
In his childhood Scrooge had been abandond in his boarding school by his parents. When he visited it with the The Ghost of Christmas Past he is heard to lament "Poor boy, poor,poor boy" on seeing the shadows of his past self
The ghost of Christmas Yet to Come, also known as the Ghost of Christmas Future, had the most profound impact on Scrooge by showing him the potential consequences of his actions and how his current path would lead to a lonely and miserable death. This vision compelled Scrooge to reflect on his life and make a transformation towards generosity and kindness.
