Nightmares Come At Night, Les Cauchemars Naissent La Nuit 1972

Two exotic dancers embark on an erotic relationship, which takes a turn when one of them starts to experience murderous nightmares that blur the line between fantasy and reality. The soundtrack is an English dub that sounds pretty awful. Have no idea if it follows the original script at all, but it is not like Franco's movies had carefully plotted, clever dialog.
