Claire Bloom had a katana, right?

The only scene I remember is the one with Claire Bloom wearing a sheer black or dark blue negligee and she was fingering a katana. Since she was a psychiatrist in this film, that was supposed to imply castration or the male fear of it which manifested itself in the lead male character as a fear of beheading. Did she also have a collection of shrunken heads? I was very young at the time so the movie was a bit over my head.
