An old dollhouse
The old dollhouse Miranda finds in their new house symbolizes the past bizarre events. Miranda realizes that the old dollhouse resembles their new house, which makes her suspicious. When she looks through the windows of the dollhouse, she sees the past events that took place in their new house for the past two centuries. For instance, a mother in the 19th century locked her daughter, Dorothy, in the attic and told people she died in a train accident. The other family that lived in the house in the 20th century during World War II experienced bizarre behaviors. For instance, the mother that used to be a good person abruptly changed to a hateful and vengeful woman.
The attic key
The attic key symbolizes a new beginning. When Miranda finds the attic key, she successfully tunes the dollhouse into the present and deletes the past. Consequently, Miranda's family is never haunted by the past. In an intriguing twist, Miranda uses the key to open the attic and finds Dorothy alive. Dorothy’s mother locked her in the attic in the 19th century and told people she died in a train accident.
The kitchen calendar
The 1904 calendar in the kitchen symbolizes the chronology of past events in Miranda's new house. When Miranda starts seeing the past events in their house, she sees a calendar in the kitchen dated 1904. Consequently, the calendar proves indeed people occupied their new houses in the last two centuries.
