It is an autobiographical detail. The director character is a self-insert for Dario, who came up with this movie after he got fired from an opera production he was directing on account of it being too violent. Leaving the opera house and going to the Swiss Alps (the site of his previous film, Phenomena) is for me him expressing that he is going back to where he belongs as an artist. You will notice that too in the final scene the director character is filming a fly, a reference to JCon and her bugs in Phenomena. The fakeout death scene in the burning house is lifted directly from the novel Red Dragon. Dario was mad that Michael Mann didn’t use it for his “Manhunter” adaptation of the novel so decided to do right by it. I believe the ending with Betty and the lizard is another self-insert moment for Dario. Contrary to the memes about him being a sadist he is a vegetarian and likes animals. Betty helping the lizard and stating her desire to escape society and not go back to doing operashit, I think it is the director talking through her mouth. His father died during the production so he was overwhelmed and wanted to be alone.
