The day I started believing in Corey (Not even 99%), was when I experienced first hand what he was talking about, 1 month before the episode aired and I actually watched what he was saying was happening to people.
In my dream, I was taken to some sort of classroom by a very bright light, lots of other people were there studying, and I was placed at a table, told the reherse words in a language i've never seen or spoken.
He said this exact thing was happening to people all around the globe.
Believe me or not, I don't care, I know what happened and that's enough for me.
