Personal question
 

After watching many Japanese horrors back to back...do you find yourself , when someone asks you question, nodding and saying 'Mmn'- instead of the usual 'yeah'?

Do you start to understand some of the dialog without reading the subtitles?

it seems that way for me but i'm just really reading the subs so quickly that i dont realize i'm doing it.

and once you dont realize you're doing it - you're used to who's voice is coming from whom and it feels like you're understanding them ... i know -it's kind of weird.

To Understand The Dialog
You Must Speak The Japanese
Or Have An Interpreter Handy
To Put Your Mind At Ease

For me, I watched Bleach, and the Death Note. So I found words like Shinigami popping out at me.

Yes.
Because of Korean movies i know a lot of Korean words, same with Thai, but of course im also using Rossetta Stone for Thai.
