Okay, I don't know how, but I managed to run out of new dreams during the 1st campaign?!
So far I've finished: I-1-3,5,6,9-19 and 21.
I have a couple of old ones that I've just been going through again to no avail, trying to find something I might have missed.
So, how can I proceed with the game? Is there any sort of diagram showing which dream leads to which or can anyone point me to the dreams leading to I-4,7,8 or 20?
Cheers!
You either did not finish Dream I-15 or omit gaining new Gate Tiles from it.
