Theresa was Boone's childhood nanny. Boone loved to torment her by calling her up the stairs all day. One day, when Boone was 6, she fell down the stairs and broke her neck. Boone felt responsible for this. It is not known whether the fall killed her. ("Deus Ex Machina")

In his dream, Locke sees Boone repeating, "Theresa falls up the stairs, Theresa falls down the stairs," before Boone told him this story. It is this revelation that leads Boone to believe Locke's dream is more than just a dream.
