The spirit first shows Scrooge a funeral scene, with businessmen wondering about the money that the dead man has left. The Ghost then takes him through dark alleyways to a scene of three people picking through the belongings of the deceased. Scrooge recognises that his own death could be met this way.
Next the Ghost takes him to the Cratchit household where Scrooge is upset to realise that Tiny Tim has died.
Finally the Ghost shows him a tombstone engraved with the name: Ebenezer Scrooge. Clutching at the spirit's robes, Scrooge pledges to change his ways if he can avoid this solitary death. The Ghost disappears and leaves Scrooge clutching at his bed curtains. Scrooge's home in stave one is dark, cold, and unwelcoming. Therefore, it represents the social isolation which he craves and acts as his sanctuary from the rest of the world. Scrooge's gravestone in the fourth stave is symbolic of his heartless and miserly ways.
Hope this helps :)
