How does Scrooge transfer his feelings about his boyhood self back to the present?

Well the Ghost of Christmas Past represents memory. The aged appearance of the childlike figure touches on the role of memory as a force that connects the different stages of a person's life. His glowing head suggests the illuminating power of the mind. The ghost initiates Scrooge's conversion from anti-Christmas meanie, to a poster boy for the holiday season. Each episode in the montage of scenes shows a younger Scrooge who still possesses the ability to love, a person who is still in touch with his fellow human beings. As the visions pass before him, Scrooge watches himself become ever more cold and greedy until the ultimate scenes. His all-consuming lust for money destroys his love for Belle and completes his reversion to a spiteful venomous recluse. The tour through his memories forces Scrooge to recall the emotional episodes of his past. This dreamlike series of hallucinatory home movies brings the otherwise hardened man to tears. This breakdown and the reconnection with his feeling self initiates the process of melting away Scrooge's cold bah-humbug exterior.
