The movie is so surreal and elusive that any messages are buried deep within. Perhaps: "curiosity killed the cat"? Other themes will be up for discussion.
Positive Role Models & Representations
We see a realistic car crash, and a few nightmarishly scary images. Otherwise, there are a few moments of characters yelling or arguing with one another.
A scene takes place at a strange, mysterious club in which women perform on stage. We hear the sounds and see some suggestions of one woman masturbating, while many men watch. The main character has sex with his girlfriend more than once; her breasts and bottom are shown. A pregnant woman is shown undressing, and her breasts are on view. Characters have sex with more than one partner. In a nightmare sequence, a fully naked woman with a spider head walks toward the camera (upside-down, on the ceiling). A character follows a strange woman down a hallway, with a close-up on her behind (she's wearing a kind of sexy, fishnet outfit).
Language is not heard very often, but in the film's final third, "f--k" is used several times. "S--t" is also heard once or twice.
Ease of Play
Characters drink casually, at home, in a background way. A woman says, "I think I'm drunk" in one scene, and goes to bed.
