The ghost of Christmas past is one of three spirits that visited Ebenezer Scrooge in Charles Dickens' classic Christmas tale, "A Christmas Carol." The ghost of Christmas past takes Scrooge back to his childhood and early adulthood, showing him memories of his life that he had forgotten or chosen to ignore. The ghost helps Scrooge see how his choices and actions have led him to where he is today, and how he can change his future.
