YOU SAID:
i cant see that movie it has frightened me
INTO JAPANESE
私はその映画が私を怖がらせているのが分からない
BACK INTO ENGLISH
I do not know that the film is scaring me
INTO JAPANESE
私はその映画が私を怖がらせていることを知りません
BACK INTO ENGLISH
I do not know that the film is scaring me
That didn't even make that much sense in English.
