"Live Action", huh? One time I had a nightmare that incorperated elements of Monsters Inc, Metroid Prime, and quite a few other computer generated things I had sitting around in my head. That was a scary nightmare, too.
Anyway, I haven't watched enough anime to have this talent myself
but I say it's pretty cool. Personally, when I am reading a book I tend to give the main characters the appearance of semi-random people I see in school. One time, I assigned the face of a girl I didn't even know from school to a character in a book, and that character was very friendly, helpful, encouraging, and all around good person. So guess what? The next day I go to school, see that girl and think "Oh yeah, I know her! She's a really good person...
No, wait.."
