Nina, in the film Nosferatu, has an apparent connection to Nosferatu. It is ambivalent to who her love is drawn towards. When she is awaken in the middle of the night, she proclaims that "he is coming, I must meet him," but this only comes after the scene of Nosferatu's ship. Also, Nina waits by the shore to await her "lover," but it is Nosferatu, not Jonathan, who is arriving by sea. There is also the scene when Nina and Nosferatu see each other through the windows and it appears that they are both enthralled by each other's appearance. Nina reacts to this scence by grasping her breast, which can be interpreted as a sign of submission to Nosferatu.
What these happenings might suggest is that Nosferatu has mental control over Nina, or it could just be both their expressions of love, which is supported by the scene where Nosferatu admires the picture of Nina and her neck.
Nosferatu can also be seen as the symbolic representation of war. He enters a foreign land and brings upon the land rampant death. Much in the same way, countries in World War I were massacred by heartless invaders many times seeking victory for no purpose but victory itself.
I enjoyed Nosferatu because I never knew where Dracula had originated. It was interesting to see the original interpretation of the novel and as a silent film. With silent films many of the feelings and interactions are inferred through facial expressions, movements, and lighting of the scenery. Nosferatu used these techniques quite well. The shadow shots of Nosferatu entering Nina's room is a classic mode in conveying the feeling of imminent danger.
