Amongst non-horror movies that are likely to induce nightmares, war films are perhaps the most likely contenders.
Sam Peckinpah's Cross of Iron (1977) tells the story of a WW2 German battalion facing off against the Russians on the Taman Peninsula.
This scene (text from Wikipedia link above) was rather uncomfortable to watch...!

When his battalion is ordered to retreat, Stransky does not notify Steiner's platoon, abandoning them. Making their way back through now enemy territory, the men capture an all-female Russian detachment. While Steiner is busy, Zoll (Arthur Brauss), a despised Nazi Party member, takes one of the women into the barn to rape her. She bites off his genitals and he kills her. Meanwhile, young Dietz, left to guard the rest of the women alone, is distracted and killed as well. Disgusted, Steiner locks Zoll up with the vengeful Russian women, taking their uniforms to use as a disguise.
