There is no sex or nudity. However, the plot may be considered suggestive for viewers due to the fact it revolves around themes of voyeurism, stalking, and sensuality. (The man is unmarried; the woman is his friend's wife).

The protagonist's obsession with a dead woman makes his actions in the second half of the film seem necrophilic. But this perversion is never made explicit.

The main character cajoles a woman into changing her appearance in order to look more like his dead lover. There is nothing explicit in the scenes but the director described it as a "reverse strip tease" since there is a clear sexual component to his desire.

In the opening scene, we see a policeman fall to his death from a rooftop. The impact is not shown but the aftermath is shown from a high distance.

Little drinking and smoking is shown.

Early in the film, Scottie (the protagonist) makes a joking reference to drowning his troubles in alcohol. As the film progresses, there is an unstressed suggestion that he really does.

The nightmare sequence is very frightening.

By today's standards this is a PG-13 for emotional intensity and sensuality.

At the opening of the movie, we see a woman's eye with the swirling vortex of terror in the pupil.

The film is very atmospheric, with music heightening the suspense throughout. There are intense, hallucinatory dream sequences, and a disturbing supernatural theme, of a living woman becoming possessed by a dead one.
