Full frontal female nudity from three actresses (the lead, a supporting character and an extra).

Some blood here and there. Nothing gory.

A woman attempts to cut herself in order to escape the nightmare. We don't see the impact of the sharp material to her wrists, but because she is also in a dream, we see that the object left no marks on her.

A few scenes show domestic abuse.

Many usages of fuck, shit, damn and sacrilegious expressions.

Jane's mother is frustrated at God and yells to the camera, "Wake up, Lord!" (played for laughs)

Consumption of alcohol and cigarettes are seen throughout the film.

The film is a psychological thriller. Most of its shock factor is not from the jump scenes, but rather on the display and mentality of the characters. Definitely for aduts only.
