Although we haven’t seen the entirety of The Hour of the Wolf, I have a few theories about Johan and Alma’s supernatural experience. In the beginning of the film, Alma is interviewed about the strange death of her husband. During this interview she says that she and Johan were looking forward to a peaceful summer on the island without any other people around. This leads me to believe that the aristocrats in the castle and the little boy on the rocks are not, in fact, real people but are visions seen only by Johan. These specters seem to represent events from Johan’s past that cause him an immense amount of guilt and anxiety. Each vision seems to remind Johan of a specific part of his psyche that he has repressed and not shared with Alma. For example Veronica represents his part in an adulterous affair and the little boy seems to embody his homosexual pedophilic desires.
What then brings about these horrific visions? I believe that Alma’s pregnancy has led Johan to question his existence; his past, present and future. Perhaps his own guilt and regret have led him to question his decision to marry and procreate. Whatever it was that brought about Johan’s unrest, his drinking, sleeplessness and sickness all contribute to his eventual lapse into total insanity. The movie, which is based upon Johan’s diary entries, is then not a real account of the summer but rather a representation of his own crazed delusions.
