If my dreams would be that boring, I would simply stay awake till I get some real trippy stuff going on in my mind. Verdict: pseudo-artsy-intellectual movie that achieved mainly one emotion in my soul: boredom by torture (if this of course was/is the aim of writer and director, they did well). Some introspective scenes including some nudity and violence don't make something good by itself, and even Mr. Dafoe's acting skills could not save this movie for me - and I really like some of his more experimental and trippy movies like The Lighthouse (2019, also directed by Abel Ferrara) or Antichrist (2009, Lars von Trier).
