6. Possession (1981)
The Possession is a storyline, camera movements and colors thrown into hyperactivity. What we get is something enthralling, headache-inducing, erotic and outrageously disturbing.
A husband returns from secret government work only to find his wife behaves inexcusably strangely. Possession is definitely something you should see repeatedly. Excellent acting performance coupled with migraine-inducing metaphorical horror and dreamily fluid camerawork makes it a true wonder of the imagination. Its infamous miscarriage scene is sickening and painful, yet confusing. Just be aware though, the movie can mentally damage you; if you try too hard to understand it the first time.
