I'm loving this so far. I much prefer Sayman's black comedies to his more horrors. The strange/dark comedy of things like this and Voynich Hotel appeals to me. Still, I can see how his style isn't for everyone...
Personally, I burst out laughing over the moth joke. I'm not sure why, but the visual gag- of the moth hatching in sync with her outburst of emotions- just struck something in me. I just assumed the cocoon in the mouth was a reference to "Silence of the Lambs", where they find a Gypsy Moth cocoon in the mouth of one of Buffalo Bill's victims.
