In the desert, I have solved the underground maze and the graveyard and the sub dream that leads to, and have seen the dream 1 card in the stand of the main dream area, but I can't get the second one. I seem to be having a problem with the blue-walled-maze sub dream, unless it doesn't have a "solution" and there is another sub dream to solve, but have seen no indication of a second puzzle.

Update: Found Vinyl #5 in blue-wall-maze and assumed that when I had both vinyls from what I assume is Act 1, that another portal in the main area would appear. No luck. Anyone have any ideas?

Update: Scratch all this. Found what I needed.
