The Dreams
I recently watched this and I loved the dreams. I liked how grounded on reality they were while still being very unsettling. For instance, Jenny dreams all her patients are gathered in a little room in her apartment, and she has to see them one by one, while Tomas, with his smug smile, stands at a corner, watching in silence. So simple and yet it's so claustrophobic!
After watching this movie and The Hour of the Wolf, I think Bergman had a natural talent for dark fantasy and horror. It's a pity he never explored those talents much in his work.
This world is a comedy to those that think, a tragedy to those that feel.
