I saved this dream for last - this was my 17th new dream. And I got ridiculously lucky with the map tiles, apparently. I played this dream for a long time until I realized there was no fail state given the scripts I could access repeatedly and the decks I had. I was able to activate any chosen items I wanted and remove the remaining items from my storage. I thought this would be a much longer, much more arduous goal using the Warehouse, but with the Sanctuary script this was trivial to complete. If you're wondering how I handled the morphings, well, let's just say I had the right progress card.
All I can say is that I am happy that I waited to play this dream and that I don't need to replay it.
When visiting the dream, you randomly pick 4 from the 8 total map tiles, so you should still have 4 more tiles to explore.
