uhhhhh
I can also kind of see this.
I didn't really reflect on the movie afterwards because of the spoiler, tbqh.
It explains why the real estate lady was so disgusted with him in their brief moment together, and why the apartment looked like it had just been painted, cleaned, etc. - because why would that be necessary if he had completely hallucinated everything? At the same time though... people renovate property before selling it, so I dunno.
My interpretation when posting this topic was that everything happened in his mind. All of the events we had seen unfold in the movie were what Bateman imagined/hallucinated while drawing tiny sketches in his day planner that Jean is looking at near the very end of the movie. The long monologues he had given were always about a song or album - and I took that as what he was listening to on his tape/CD player while drawing the sketches.
But I like this better!
