I'm at the quest, At the summit of apocrypha, and it tells me to read the waking Dreams black book. However when I read the book it does nothing, all the other black books I own take me there except this one. I've tried reloading the game and previous saves but nothing has worked. This book for me is completely bugged. The only time I have been there is for temple of miraak quest where he kicked my butt. And a second time I reread that book to enter apocrypha right after being kicked out by miraak. Now it seems I cannot reenter that place at all.
Anyone have any solutions?

I have the exact same problem! I have 2 copies of the book for some reason do you? I thought that's what is causing it for me but obviously not.

I only have 1 copy of the book. I have just resorted to finishing the rest of the quests for the dlc hoping there is going to be a patch soon

Me too, we can only hope.

I have the exact same issue: one book only, but when reading it, nothing happens. Unfortunately, I've already completed essentially every other quest in this DLC. If I had to go back, I'm screwed. I don't even think I have a saved game from which to do that...

Spoiler

After getting the last of the new Bend Will shout and reading the Awakening Dreams book

my character just stands there and does nothing forcing me to revert to a previous save state.

Also, the first three Ash Spawn encountered in "March of the Undead" take no harm making the quest impossible
This is my first play through on this DLC. I hope they fix it soon
