I went through the tight passage on one of the Y cards, both characters were on that tile. I didn't want the dream to end so I suffered the wounds and sealed the cards. I discard all the tiles without dreamers on it (so the remaining X, Y and Z tiles). All that remains is the Y card I'm standing on.
Now I can't perform exploration because it's impossible to be far enough to explore? I have nowhere to go other than to leave the dream anyway, is that right?
Note that s550 says you “may” suffer ...hence it is optional and not required.
> Yes, you can choose the first or the second option:
You may end this Dream instantly – s.216.
OR
You may suffer 2 Distress and Seal 3 cards
to discard all Exploration tiles without any Dreamers to the Exploration tiles pool.
Or you can choose not to choose any of them and just keep playing.
