Trippy Anime Intros - Subliminal Messages?

[Ran]

Japanese Release Title: Higurashi no Naku Koro ni (Trans: When the Cicadas Cry)
English Release Title: When They Cry

A dark, bloody, and violent series about school kids, demon possession, murders, lies, tragedy, cover-ups and more. The intros are pretty sweet alone, but this is just cool.

Sound familiar?

Apparently there is some way to decipher the chanting into the Japanese phrase "nigerarenanai". I can't find the link at the moment, but the phrase translates into "You can't escape" or something like that.
