Sure, will give it my best summary, from what i can remember
Best guess is an older japanese film, possibly 80s or 70s, a group of men infiltrated this woman's house and had her friend knocked unconscious. He wanted her to look at a light and threatened to kill her friend if she didn't. She reluctantly looks at him after keeping her eyes from looking, then he uses a light reflection on his sword, mentions something about a 'dreamy spell' and hypnotizes her with light reflection
The actress did amazing, the way she gives in, going from defiant to passive etc. I've always wanted to revisit but couldn't remember the title or any notable lines from the subtitle other than 'dreamy spell'
Wish i could remember the names of the characters, and give a better description, but thats all i got. Apologies >_>
