Black books, waking dreams, chapter 6 help?

I've looked online for answers but this is frustrating now. I already know all the bend will shouts, unlocked I mean, and I'm standing here at the gate just staring through. I can't get outside. I've also already unlocked dragon aspect, so please help? There is nothing to open this gate manually.

EDIT: took this for you guys though I don't think it helps. Just to give you an idea of what I mean. http://i.imgur.com/CaVe20S.jpg
