Laura begins her tale by relating her childhood in a "picturesque and solitary" castle in the midst of an extensive forest in Styria where she lives with her father. When she is six years old, Laura has a vision of a beautiful visitor in her bedchamber.
12 years later, Laura and her father are admiring the sunset in front of the castle when her father tells her of a letter he received earlier from his friend General Spielsdorf. The General was supposed to bring his niece, Bertha Rheinfeldt, to visit the two, but the niece suddenly died under mysterious circumstances. The General ambiguously concludes that he will discuss the circumstances in detail when they meet later.
Laura is saddened by the loss of a potential friend, and longs for a companion. A carriage accident outside Laura's home unexpectedly brings a girl of Laura's age into the family's care. Her name is Carmilla. Both girls instantly recognize the other from the 'dream' they both had when they were young.
