Okay, this is a longshot, but I am going to guess "Spellbound" by Estée Lauder.
Here's why. Magritte's "La Trahison des Images" isn't a film, nor is it bloody, so I decided to start with surrealism and horror in film and go from there.
One thing that occurred to me is that there is a surrealistic dream sequence in the Hitchcock film, "Spellbound." As a matter of fact, Salvador Dali was a consultant on that film, and helped to design that dream sequence. So, yeah. "Spellbound" is my best guess so far.
